High compression ratio is desirable because it allows an engine to extract more energy from air-fuel mixture due to its higher engine temperature/heat efficiency. And because internal combustion engines are heat engines, higher efficiency is created because higher compression ratios permit the same combustion temperature to be reached with less ...

In some cases the pressure rise can be so great that it causes an audible pinging noise from the engine. As the engine rpm increases, the pressure in the cylinder becomes so great that pumping losses occur to the piston. That is why engines with too much spark advance or too high of a compression ratio, run flat at high …

This is the basic principle of ignition in a compression ignition engine. The compression ratio is high enough so that the temperature rises above self-ignition temperature (SIT) during the compression stroke. Self-ignition then occurs when fuel is injected into the combustion chamber.
Here's What 'Compression Ratio' Actually Means And Why It Matters
We didn't use any coatings, exotic rotating assembly or valvetrain pieces, high compression that would live only through the dyno pulls, or do things that we wouldn't normally do for a good reliable pump gas, street/strip engine. Because of this, we had to spend very little time from specing the engine to …

High compression engines may exhibit spark knock at wide open throttle. Spark knock can often be eliminated by adding more fuel (AFR in the 12.0-12.5 range) within the affected RPM range. If throttle roll-on response is poor or a lean transient (high AFR values) is observed, try using a higher value for acceleration enrichment. Decel Popping

This very important concept of compression-ignition can be credited to Rudolf Diesel (1858-1913), a German engineer born in Paris. In 1892 he proposed compression of air alone until a sufficient high temperature was attained to ignite the fuel which was to be injected at the end of the compression …

For a typical internal combustion engine, the thermal efficiency is a function of engine compression ratio, air specific heat ratio, k. The maximum thermal efficiency of the 3.5 HP engine in the ME 115 lab is approximately 20% and varies with speed, load, and fuel mixture.

In many cases the results are astounding. Our 622 engine uses the Profiler 2/4 tunnel ram intake. This manifold is tuned from 7400rpm to 8700rpm. The larger engines all operate from 6000rpm to 7500rpm and some as high as 8000rpm. So the engine is trying to …

The larger ports work best at high rpm because that's where we have air velocity, which makes torque. Closed chambers yield higher compression ratios, which means power. The 351C-2V head is designed for low-rpm street use. It's perfect for a street driver because the smaller ports provide air velocity at lower engine …

When high compression ratios are used, the temperature of the air-fuel mixture in an SI engine rises above the autoignition temperature of the fuel (the temperature at which the fuel ignites without the help of a spark) during the combustion process, causing an early and rapid burn of the fuel at some point or points ahead of the flame front ...
