The three things that will help you're knocking problem are: 1. Retard the timing. 2. Use higher octane fuel 3. Lower the combustion temp by adding an EGR valve, or making sure the one you have works. I'd assume the EGR valve is not something that you want to do. I wouldn't. Obviously, "4" would be swap out the heads to ones with a bigger combustion chamber thus reducing the compression. A lean mixture will give you a "lean misfire".
What else can I help you with?
What is the effect of air fuel ratio on detonation in internal combustion engine?
A leaner fuel mixture burns hotter than a rich mixture. so a leaner mixture will be more prone to detonation than a richer mixture.
What change occurs in the fuel air mixture when carburetor heat is applied?
It get's richer, The fuel/air mixture becomes richer..
What change occurs in the fuel-air mixture when carburetor heat is applied?
It get's richer, The fuel/air mixture becomes richer..
What is the fuel mixture?
The fuel mixture refers to the combination of fuel and air that is used in internal combustion engines for optimal combustion. In gasoline engines, it typically consists of about 14.7 parts air to 1 part fuel by weight, known as the stoichiometric ratio. For diesel engines, the mixture is generally richer in fuel, as they rely on compression ignition rather than spark ignition. The precise mixture can vary based on engine design, operating conditions, and desired performance characteristics.
How does a choke work?
By cutting off part of the supply of air. This will cause the fuel/air mixture to be very rich. A cold engine needs a much richer mix than a warm engine. Once the engine warms up the choke opens up and the fuel/air mixture is restored to the optimum mix.
Why is it that when you turn the car off its still running?
Could be that your idle speed is too high, or engine is running too hot causing the PMC to deliver a richer mixture,
How does the choke work on a Daewoo matiz?
The choke on a Daewoo Matiz helps to enrich the air-fuel mixture during cold starts by restricting airflow into the engine. This creates a richer fuel mixture, allowing the engine to start more easily when cold. Once the engine warms up, the choke gradually opens, allowing normal airflow and fuel mixture for optimal engine performance. In many models, the choke is automatic and linked to the engine temperature to facilitate this process.
What causes Snow thrower engine to stop when engaging auger?
Check the fuel and air filters. If they are clean, open the carburetor needle valve 1/8 turn for a slightly richer mixture to handle the extra load on the engine when the auger is engaged.
Idle fuel mixture setting for 68 250 Chevy?
the best way to set the idle mixture screw is with a gas analyzer. setting the mixture to 14:1. if you dont have one use a vacuum gage and set for the highest vacuum. If you dont have one of them then turn the screw in til the engine starts to stumble. then turn the screw out til the engine starts to stumble. turn the screw back in half the distance. that will be your best setting. Any leaner and the engine wont start, any richer and the engine will flood.
Do you need to adjust a carburetor for high elevation?
Yes, the hire you go the less air, your engine will run richer and richer.
Is the carb adjustment screw on a Yamaha sh50 in or out to richen the mixture?
To richen the mixture on a Yamaha SH50, you should turn the carb adjustment screw out (counterclockwise). This allows more fuel to enter the mixture, resulting in a richer fuel-to-air ratio. Conversely, turning it in (clockwise) would lean out the mixture. Always make small adjustments and test the engine's performance after each change.
How do you adjust Tecumseh LH195sa?
To adjust the Tecumseh LH195SA engine, first, ensure the engine is off and cool. Adjust the carburetor’s idle speed screw to set the desired RPM while the engine is running; turn it clockwise to increase speed and counterclockwise to decrease speed. For the air-fuel mixture, adjust the mixture screw, turning it in for a leaner mix and out for a richer mix, until the engine runs smoothly. Always consult the engine’s manual for specific settings and adjustments.
