GDI Engines and Carbon Deposits | Know Your Parts


we’ve created this program to help you
better serve your customers with gasoline direct injection engines GDI
engines have a problem that can seriously hurt your customers vehicle
performance and fuel economy but the solution is fast and easy for you and
it’s affordable for them to go through the program use the navigation buttons
at the bottom right and watch for a couple of quick quizzes along the way
let’s get started in the past decade gasoline direct
injection engines have become extremely popular with both domestic and import
auto manufacturers compared to conventional fuel injection Gidi I can
deliver improved fuel efficiency more power from smaller engines and reduced
emissions at low load that’s great but the popularity of GDI engines has
brought back an old service issue carbon deposits that can rob drivers of
horsepower gas mileage and smooth operation so why do carbon deposits
happen in GDI engines and how can you help your customers let’s have a look
conventional multi-point fuel injection injects fuel into the intake tract or
cylinder port at low pressure with gasoline direct injection or GDI a
common rail fuel line injects highly pressurized gas directly into the
combustion chamber of each cylinder the improvements in power and fuel economy
come from the extremely precise control that GDI engines have over the amount of
fuel delivered and injection timing fuel and timing are adjusted multiple times
per second according to engine load plus some GDI engines operate on full air
intake with no air throttle plate which further improves efficiency and reduces
piston pumping losses instead of having a throttle plate that restricts the
incoming air supply the engine speed is controlled by the ECU and the EMS which
regulate fuel injection function and ignition timing but as with many
technology advancements there’s also a downside when conventional multi-point
fuel injection injects fuel into the intake tract or cylinder poured gasoline
washes over the back sides of the valves modern gasoline with its package of
detergents is an excellent cleaner so in conventional engines gasoline keeps the
back sides of the valves clean and free from deposits but since GDI engines
inject gas directly into the cylinder gas never reaches the back of the valves
when fuel is no longer washing the intake valves on the way to the cylinder
small amounts of dirt from intake air and blowback carbon from the crankcase
inhalation system build up and burn onto the intake walls the result is carbon
deposits forming on the valves cylinder heads and injectors and that’s where the
trouble begins over time the carbon buildup on the intake valves reduces the
air flow to the cylinders and that reduces torque and horsepower and Hertz
fuel economy the carbon deposits on the cylinder in cylinder head can cause
pre-ignition rough starting and rough idling as well as foul spark plugs and
misfire codes the build-up can become so severe that
pieces of carbon can actually break off and burn a hole in the catalytic
converter many modern GDI engines face a double
challenge because they’re variable valve timing keeps the valves open longer to
maximize the scavenging effects and minimize emissions that leaves the
valves exposed to carbon particles in the cylinder longer and that means more
carbon buildup how big of a deal is the GDI carbon deposit problem it’s big and
it’s becoming huge gasoline direct injection was actually first invented in
1902 by the French inventor Leon lava sir who also produced the world’s first
v8 engine but as of 2008 only 2.3 percent of passenger vehicles used GDI
engines by 2015 the number was up to 45% by 2021 roughly 80 million vehicles in
the US will have GDI engines and more cars with GDI engines means more service
issues related to carbon deposits and that means more customers who need a
solution until recently removing carbon buildup on GDI intake valves had been
difficult in costly labor-intensive processes such as walnut-shell blasting
and manual valve cleaning required an engine teardown to access the valves it
was hard work and a very hard sell to many drivers before GDI engines became
popular fuel additives were used to treat carbon buildup but with GDI
neither the additives nor the fuel would reach the back of the valves but CRC has
an affordable solution that your customers can easily get onboard with
scientists have found that the chemical polyether amine or peña when applied in
strong concentration and under the right conditions can effectively clean
hardened carbon deposits from GDI valves and other engine services without
blasting brushing or any teardown required CRC has used this discovery to
create a GDI carbon deposits solution that allows you to tackle the problem
quickly easily and at a very reasonable cost
CRC GDI IVD intake valve and turbo cleaner is an aerosol spray that’s
applied through the engines air intake or throttle body and delivered directly
to the backs of the GDI intake valves CRC GDI valve and turbo cleaner contains
the highest concentration of peña available on the market to provide the
fastest most thorough chemical cleaning available a single application removes
up to 46 percent of carbon deposits in the first 60 minutes with the ability to
clean heavily baked-on carbon deposits the way it does you might ask is it safe
yes CRC GDI valve and turbo cleaner is safe and effective for all gas-powered
engines including turbocharged and supercharged engines it’s safe to use
every 10,000 miles or at every oil change and it’s safe to use 402 sensors
and catalytic converters but it should not be sprayed directly on a mass
airflow sensor and should not be used in diesel engines high temperatures can
cause carbon to stick to turbocharger turbines housings and waste gates the
turbine blades and oil seals are fragile and carbon buildup can eventually cause
significant damage but the same cleaning action that removes carbon deposits from
valves and pistons cleans turbo impellers as well on turbo engines CRC
GDI valve and turbo cleaner can be sprayed directly through the throttle
body or through the air intake but again never directly on a mass airflow sensor
okay here’s some real-world independent lab results that prove the effective
cleaning power of CRC GDI valve and turbo cleaner
here’s a 2011 Hyundai Sonata cylinder-head before treatment before
treatment the carbon deposits average nine point eight nine mils in thickness
you know that’s going to contribute to a tendency for pre ignition now here’s
that same cylinder head after an hour of treatment with CRC GDI valve and turbo
cleaner the carbon deposits are nearly gone the average thickness is down to
one point five mils the deposits were reduced by eighty-five percent after the
first hour now have a look at the intake valve from the same Sonata after the
first hour of treatment the deposits are reduced by 24 percent take a look at
these fuel injectors also from a 2011 Sonata before treatment they’re heavily
caked with carbon and the flow is being impeded around the injector orifice
after the treatment the valves look almost new a hundred percent of flow has
been restored and the spray pattern and fuel droplet size are once again
optimized for increased fuel economy here’s a cylinder top from a 2009
Cadillac CTS carbon deposits average eight point five nine mils in thickness
after the first hour of treatment the deposits measured two point seven seven
mils a 68 percent reduction in deposit thickness you might wonder why these
test results say after the first hour that’s because the carbon cleaning
action will continue for several days after the treatment as the car is driven
additional carbon that’s been loosened by CRC GDI valve and turbo cleaner is
safely removed by the heat and pressure of engine operation take a look at these
dynamometer results for a 2015 VW Passat 1.8 eye for turbo the vehicle measured
an impressive 5.6 peak wheel horsepower gain two days after treatment but it
picked up an additional six point nine peak wheel horsepower gain when measured
eight days after treatment here’s another bonus CRC GDI valve and
turbo cleaner will also work to clean carbon deposits off spark plugs without
the need to remove them from the engine and finally here’s proof that CRC GDI
valve and turbo cleaner does really work for turbos here’s a 2013 Mini Cooper
countryman turbo impeller before treatment and here it is after treatment
the results are dramatic you can see all our test results at CRC
for shops comm the tests are real and so are the results
CRC GDI IVD intake valve and turbo cleaner really does remove tough carbon
deposits from valves piston heads fuel injectors and intake manifolds quickly
safely and without an engine teardown first just as you would with any product
read the entire product label before using so you can understand the
instructions and the safety guidelines next warm up the engine CRC GDI valve
and turbo cleaner requires a period of heat soak to work so you want to start
with an engine that’s fully warmed up locate the throttle body or air intake
and spray the product directly through the throttle body if the throttle body
is not easily accessible spray past the mass airflow sensor but do not spray
into the mass airflow sensor assembly you can also remove the mass airflow
sensor assembly and spray where the sensor is mounted if the vehicle is
turbocharged you can remove the booster sensor and the charge pipe and spray
into the pipe if it’s easier you can also spray into the vacuum port lift the
permis draw dual action spray system and lock it into place with the engine
running at 2,000 rpm spray in short bursts until the can is empty once the
can is empty rev the engine two to three times but don’t exceed 3,500 rpm run it
idle for one minute then turned the engine off reassemble the air intake
system and let the engine heat soak for a full hour the heat soak is critical so
be patient and let the CRC GDI valve and turbo cleaner do its work after the hour
is up restart the engine and drive at highway speeds for at least 10 minutes
and remember as our tests showed the maximum benefit is achieved when the
vehicle is driven regularly over the next several days so let your customer
know they should drive the car regularly over the next week or so if you have a
vehicle with severe carbon buildup CRC GDI valve and turbo cleaner can even be
used in successive treatments just have your customer drive about a thousand
miles before a second treatment in order to get the full benefit of the first
treatment you GDI engines are not the only engines
that get carbon deposits conventional fuel injected and carbureted engines can
suffer from carbon buildup to CR C GDI valve and turbo cleaner is safe for use
in engines with port fuel injection or carburetors
you can apply the product in the same way as you would on a GDI engine right
through the air intake for automotive service providers the GDI carbon deposit
issue means an expanding service opportunity any time a customer comes in
for an oil change or a regularly scheduled service suggests treatment
with CRC GDI IVD intake valve and turbo cleaner it’s fast affordable and has
real benefits for your customers you’ll be helping to preserve their gas mileage
horsepower and vehicle life while adding a nice boost to your sales as well
well that’s it thanks for taking the time to learn about CRC GDI IVD intake
valve and turbo cleaner we hope you’ll make it a part of your regular service
