What is Open type combustion chamber?

Open Combustion Chamber The combustion chamber is made like a groove inside the top of the piston. The injector is fitted at the centre of the cylinder head so that it injects the fuel in the combustion chamber. The engines of Leyland buses use this type of combustion chamber.

Is a bigger combustion chamber better?

A bigger combustion chamber is not necessarily better. Enlarging a combustion chamber reduces its compression ratio, resulting in cooler burning temperatures and inefficient combustion.

What are the advantages of open combustion chamber?

The salient features of open combustion chamber are: Less turbulence is generated in this type, so heat loss is less and thus, Excess air required is more, so engine size increases, and thermal efficiency also increases, starting is easier.

What are the three types of combustion chamber?

Types of Combustion Chamber. There are three main types of combustion chamber in use for gas turbine engines. These are the multiple chamber, the tubo-annular chamber, and the annular chamber.

What are the 2 basic types of combustion chambers in diesel engines?

Compression-ignition engines, such as diesel engines, are typically classified as either:

Direct injection, where the fuel is injected into the combustion chamber.
Indirect injection, where the fuel is injected into a swirl chamber or pre-combustion chamber.

What is the best combustion chamber?

hemispherical combustion chamber
The hemispherical combustion chamber offers the best surface-to-volume ratio and tests conducted by Chrysler in 1950 showed that to match the thermal efficiency of a 7.00:1 compression ratio Hemi engine, its previous combustion chamber would need 10.0:1 at 1200 rpm, 9.4:1 at 2000 rpm, 8.9:1 at 2800 rpm and 8.5:1 at …

What did 781 heads come on?

The 781 heads are the best cast iron large oval port heads GM ever produced for the big block Chevy engine. They are worth rebuilding and respond well to pocket porting, bowl blending and larger valves. They will easily support over 500 horsepower. They are a very desirable street head.
