What kind of engine has a combustion chamber that is flat?
An engine with a flat combustion chamber is typically a flat engine, such as a flat-four or flat-six configuration, often found in brands like Subaru and Porsche. This design allows for a lower center of gravity and improved stability in vehicles. The flat layout provides a more even distribution of weight, contributing to better handling characteristics. Additionally, the flat combustion chamber can enhance air-fuel mixture efficiency and combustion performance.
What is Combustion Chamber and its types?
A combustion chamber is a space within an engine or furnace where fuel and air mix and ignite to produce energy. The primary types of combustion chambers include open, closed, and semi-closed chambers. Open chambers allow for unrestricted airflow and are often used in simpler applications, while closed chambers contain the combustion process and are more efficient, commonly found in modern engines. Semi-closed chambers offer a balance, providing some control over the combustion process while allowing for partial exhaust flow.
Does a rotary engine use a reed valve?
No, a rotary engine does not use a reed valve. Instead, rotary engines, like the Wankel design, utilize a triangular rotor that moves within an epitrochoidal housing, creating distinct chambers for intake, compression, combustion, and exhaust. The intake and exhaust processes are controlled by the shape of the rotor and the housing, eliminating the need for reed valves typically found in piston engines.
What is tdgi rephering to an engine?
TDGI refers to "Turbo Direct Gas Injection," a technology used in some internal combustion engines to improve fuel efficiency and performance. It combines turbocharging with direct fuel injection, allowing for better atomization of fuel and more efficient combustion. This results in increased power output while reducing emissions and enhancing overall engine responsiveness. TDGI is often found in modern gasoline engines aimed at optimizing performance and efficiency.
What are the advantages of spark ignition engine?
Spark ignition engines, commonly found in gasoline vehicles, offer several advantages. They generally provide smoother and quieter operation compared to compression ignition engines, leading to a more pleasant driving experience. Additionally, they tend to have a faster response to throttle input, which enhances performance and acceleration. Furthermore, spark ignition engines are often simpler in design and maintenance, making them more accessible for repairs and servicing.
Domed pistons are typically found with what type of combustion chamber?
Dome Pistons are used in 2 stroke engines.
What is an open combustion chamber?
An open combustion chamber is a type of combustion chamber found in some internal combustion engines where the combustion area is not fully enclosed by the piston and cylinder head. This design allows for better airflow and mixing of air and fuel for combustion.
What do you mean by closed combustion chamber?
A closed combustion chamber refers to a sealed environment where fuel and air are mixed and ignited to produce energy, typically found in engines and boilers. This design prevents the escape of gases and enhances efficiency by allowing for better control over the combustion process, leading to higher energy output and reduced emissions. The closed nature also helps in maintaining optimal temperature and pressure conditions for combustion.
What are the most common combustion chamber designs on mercruiser?
The most common combustion chamber designs on MerCruiser engines include the wedge-shaped and oval-shaped chambers. Wedge chambers promote better airflow and combustion efficiency, while oval chambers are known for smooth combustion and are typically found in larger displacement engines. These designs help optimize power output and fuel efficiency, catering to various marine applications. Additionally, some models may feature a pent-roof design for improved performance in high-output applications.
Is a 383 engine a hemi?
No, a 383 engine is not a Hemi. The 383 is a V8 engine commonly associated with Chrysler's small-block family, while a Hemi refers specifically to engines with a hemispherical combustion chamber design, which are typically found in Chrysler's larger displacement engines, like the 426 Hemi. While some 383 engines may feature similar performance characteristics, they do not have the Hemi design.
What is swirl chamber of an engine?
The swirl chamber of an engine is a specific area designed to enhance the mixing of air and fuel during the combustion process. It promotes a swirling motion of the air-fuel mixture, which improves combustion efficiency and reduces emissions. Swirl chambers are commonly found in diesel engines, where they help achieve better ignition and combustion characteristics, especially at lower loads. This design ultimately contributes to improved engine performance and fuel efficiency.

Is diesel engine a continuous combustion engine or intermittent combustion engine?
Type of combustion is determined by the engine, not the fuel. Intermittent or reciprocating engines such as those found in cars and trucks can run on diesel. Gas turbines AKA jet engines can also run on diesel however they are continuous combustion engines. The answer to your question depends on the type of engine you have in mind. If it has pistons then it will be intermittent.
What is the name of the small indentations either cast or machined in the piston top?
The small indentations cast or machined into the piston top are called "piston bowl" or "piston recesses." These features help improve combustion efficiency by optimizing the fuel-air mixture and enhancing turbulence within the combustion chamber. They are commonly found in diesel engines and some gasoline engines to facilitate better performance and emissions control.
What is throttle governor?
A throttle governor is a device used in engines to regulate the engine's speed by controlling the amount of fuel or air entering the combustion chamber. It automatically adjusts the throttle position based on the engine load and speed, ensuring optimal performance and preventing over-revving. Commonly found in internal combustion engines, it helps maintain consistent power output and efficiency, enhancing the overall operation of vehicles and machinery.
