What does a throttle valve do on a 6.7 Cummins?
The 6.7 Cummins throttle valve on a stock engine works together with the EGR system to re-circulate exhaust gas through the intake to lower tailpipe emissions.
What does the throttle valve do on a Cummins?
The throttle valve sits between the intake horn and the rest of the truck’s exhaust gas recirculation system. When the computer wants to recirculate exhaust gases back through the EGR, it closes that throttle valve to force some of the air through the EGR valve.
Does a Cummins have a throttle body?
Short answer: Diesels do not need throttle body and throttle plate for its efficient operation. Why? Because Diesel engine is throttled by fuel not air like in a Petrol engine.
What controls the throttle on a 6.7 Cummins?
The throttle control valve is located between the intake manifold and intercooler pipe on the drivers side of the engine and features a butterfly valve that has been known to get contaminated with soot and freeze up.
How do I clear my electronic throttle control?
Turn ignition switch “OFF” wait at least 10 seconds. Turn ignition switch “ON” and wait at least 2 seconds. Turn ignition switch “OFF” wait at least 10 seconds. Throttle Valve Closed Position Learning.
What’s a throttle valve?
: a valve designed to regulate the supply of a fluid (as steam or gas and air) to an engine and operated by a handwheel, a lever, or automatically by a governor especially : the valve in an internal-combustion engine incorporated in or just outside the carburetor and controlling the volume of vaporized fuel charge …
Does diesel engines have throttle valve?
Modern diesel engines are frequently equipped with an exhaust gas recirculation (EGR) valve and intake throttle (ITH). The intake throttle serves to depress intake manifold pressure, create a greater pressure differential across the EGR valve, and enhance the ability to flow EGR at low speed and load conditions.
Can you delete EGR without tuner?
If you do not currently have a tune you can not do a delete. Maybe you meant off road tune? The Hot Tune deleted the EGR, the off road tune deletes all emissions (EGR, DEF, DPF, SCR).
Should I delete my 6.7 Cummins?
There are two primary reasons for deleting the DPF system on the 6.7 Cummins. First is for performance purposes. Since the DPF system is part of the exhaust, it creates a lot of backpressure which detracts from performance potential. Secondly, the DPF system is prone to clogging and costs $2k+ to replace when it clogs.
How do I reset my electronic throttle control?
Resetting your electronic throttle control manually can be a tricky job. First, make sure the accelerator pedal is fully released. Next, turn the ignition on and then turn it off and wait for ten seconds. During these ten seconds, be sure the throttle valve is moving by listening for a sound of operation.
What causes electronic throttle control problems?
The most common causes of an electronic throttle control light are a faulty throttle control sensor or a faulty throttle accelerator pedal position sensor.
How much horsepower does a throttle body add?
A bigger throttle body means more air And since the engine is basically a large air pump, increasing the air intake level will increase the engine’s power output as well, in some cases by up to 15 to 25 hp.
What happens if the throttle valve of a running engine opens further?
The main fuel jet comes into action when the throttle valve is further open. Then the venturi-shaped air-flow restriction creates a reduced pressure for drawing fuel from the main jet into the air stream at a rate related to the air flow so…
How can a diesel engine provide engine braking without a throttle valve?
Diesel engine braking Unfortunately, diesel engines don’t have a throttle valve, so instead they use an exhaust valve that closes during the exhaust stroke of the engine cycle. Back pressure is then created which fights back against the motion of the pistons, slowing them down.
Do diesels have idle control valve?
The engine accelerates on its own while idling. I tried reading online and found a post that this could be because of the Idle Air Control Valve. I told this to my mechanic and he told me that my car and diesel engines don’t have Idle Air Control Valve.
Does EGR delete damage engine?
EGR Systems Have Improved But The Bad Reputation Remains What some people don’t realize is that yes, deleting an EGR system can help prevent some expensive repairs. But they can also cause major problems in other parts of your engine.
Should you delete a 6.7 Cummins?
6.7 Cummins DPF Delete Summary Overall, deleting the DPF and other emissions systems sounds like a really good idea. It prevents clogged filters, reduces maintenance costs, improves performance, and increases gas mileage.
