What do Both valves on a four stroke reciprocating engine open the?
In a four-stroke reciprocating engine, both valves—the intake valve and the exhaust valve—open to facilitate the engine's four distinct strokes: intake, compression, power, and exhaust. The intake valve opens to allow the air-fuel mixture into the combustion chamber during the intake stroke, while the exhaust valve opens to release exhaust gases after combustion during the exhaust stroke. This coordinated opening and closing of the valves ensure efficient engine operation and optimal performance.
How many valves does a 2 stroke diesel engine have and what is there purpose?
A typical 2-stroke diesel engine has two main valves: one for intake and one for exhaust. The purpose of these valves is to control the flow of air-fuel mixture into the combustion chamber and the expulsion of exhaust gases after combustion. In some designs, ports may be used instead of traditional valves to facilitate this process, allowing for a more efficient exchange of gases during the engine's cycle. This configuration contributes to the engine's compact size and power output.
Who was the 1886 German scientist who devised an internal combustion engine?
1886 - Karl Benz received the first patent (DRP No. 37435) for a gas-fueled car. 1889 - Gottlieb Daimler built an improved four-stroke engine with mushroom-shaped valves and two V-slant cylinders. 1890 - Wilhelm Maybach built the first four-cylinder, four-stroke engine.
What does incomplete combustion do to the engine of a car?
Incomplete combustion in an engine indicates that all of the fuel has not been burnt. Incomplete combustion can cause clogging and damage to the valves in the engine of a car.
What is difference between valve and port?
valves are use in four stroke engine, and ports are use in two stroke engine.
Internal-what is combustion engine used for?
a internal combustion engine is used in every make of car from racing to heavy mechanical diggers, Two types of internal combustion example two stroke mostly used for lawnmowers some motorbike's stroke used for all mechanical cars/buses/tractors /no valves in t/stroke. mostly eight valves used in cars.

What is the corret name for the types of valves used in a four stroke engine?
The correct name for the types of valves used in a four-stroke engine are intake valves and exhaust valves. The intake valves allow the air-fuel mixture to enter the combustion chamber during the intake stroke, while the exhaust valves enable the expulsion of combustion gases during the exhaust stroke. Together, these valves play a crucial role in the engine's intake and exhaust processes.
The purpose of a camshaft in an internal combustion engine is to?
Its purpose is to open the right valves at the right times.
Where is the intake valve located?
The intake valve is located in the cylinder head of an internal combustion engine. It allows air and fuel mixture to enter the combustion chamber during the intake stroke of the engine cycle. Typically, there are multiple intake valves per cylinder, depending on the engine design, to optimize airflow and performance.
Describe how the intake and exhaust valves control the flow of the intake mixture and exhaust gases?
The intake and exhaust valves in an internal combustion engine regulate the flow of air-fuel mixture into the combustion chamber and the expulsion of exhaust gases. The intake valve opens during the intake stroke, allowing the mixture to enter, while it closes during the compression stroke to seal the chamber. Conversely, the exhaust valve opens at the end of the combustion cycle, enabling the spent gases to exit the chamber as the piston moves upward. This precise timing and operation of the valves ensure efficient engine performance and optimal combustion.
Which valves are open on the compression stroke?
During the compression stroke of an internal combustion engine, both the intake and exhaust valves are closed. This closure allows the piston to compress the air-fuel mixture in the cylinder, increasing its pressure and temperature in preparation for ignition. The intake valve remains closed to prevent any backflow of the mixture, while the exhaust valve is also closed to contain the combustion gases until the power stroke is completed.
What is the hottest part of the exhaust system?
The exhaust valves are the hottest component of the exhaust system of an internal combustion engine.

This coordinated opening and closing of the valves ensure efficient engine operation and optimal performance.
What are the names of the strokes on a two stroke engine?
A two-stroke engine is an internal combustion engine that completes the process cycle in one revolution of the crankshaft (an up stroke and a down stroke of the piston, compared to twice that number for a four-stroke engine). This is accomplished by using the beginning of the compression stroke and the end of the combustion stroke to perform simultaneously the intake and exhaust (or scavenging) functions. In this way, two-stroke engines often provide strikingly high specific power, at least in a narrow range of rotational speeds. The functions of some or all of the valves required by a four-stroke engine are usually served in a two-stroke engine by ports that are opened and closed by the motion of the pistons, greatly reducing the number of moving parts.
