For a conventional gasoline engine, the higher the compression ratio, the more efficient the engine. US passenger cars have not had very high compression ratios for about 30 years for multiple reasons. During 1970-1972, Chrysler had the highest compression ratios in US production cars, requiring the highest octane gasoline to operate properly.

Which engine is the most efficient in terms of compression ratios?
Diesel engine
What should the compression be on a 1986 na Nissan 300zx?
The compression ratio for a 1986 Nissan 300ZX with the naturally aspirated (NA) engine is typically around 8.3:1. It's essential to maintain this ratio for optimal performance and efficiency. If you're checking compression in terms of pressure, healthy cylinder compression readings should generally be between 140-160 psi. Variations from these numbers can indicate engine wear or issues that may need to be addressed.
How much compression should a ktm 65 sx have?
A KTM 65 SX should typically have a compression ratio of around 12:1 to 14:1. In terms of actual compression pressure, it can range from 120 to 150 psi when tested with a compression gauge. Maintaining proper compression is crucial for optimal performance, so ensure that the engine is in good condition and that the piston and rings are not worn. Regular maintenance and checks are recommended to keep the compression within this range.
Does a head gasket make an engine lose compression?
Verification on your question: Do head gaskets make cars lose pressure....hmmmmm, I think what your asking is.... Does a head gasket make an engine lose compression. - Correct?The simple answer is yes, it does, but it is by design. The amount the head gasket lowers the compression (or pressure) is built into the overall design of the engine. For instance, if you were to assemble the head to the block, without a gasket, you would raise the compression (pressure) slightly and potentially cause damage to the engine. This would most likely become apparent when you burn out a valve or burn a hole in the top of a piston.In general terms: - The greater the compression ratio, the bigger the explosion in the bore and the more heat that is produced.
What is this difference between static and dynamic compression in 5th grader terms?
Static or cranking compression pressure is what each cylinderexperiences when the starter motor is turning the engine or whenthe engine is running at idle RPM. Dynamic compression is measure with all plugs installed but one. The compression is measured at that one plug hole when the throttle is snapped open for a split second.
What are the relations between the golden ratio and the Fibonacci series?
The ratio of successive terms in the Fibonacci sequence approaches the Golden ratio as the number of terms increases.
What do you call the numbers in a ratio?
the numbers in a ratio called TERMS
How is the golden ratio devised?
The 'golden ratio' is the limit of the ratio of two consecutive terms of the Fibonacci series, as the series becomes very long. Actually, the series converges very quickly ... after only 10 terms, the ratio of consecutive terms is already within 0.03% of the golden ratio.
Compression is the part of medium where are the particles?
In terms of particles, "compression" means that particles move closer together.
How do you express 33.3 percent as a ratio in lowest terms?
33.3% as a ratio in lowest terms would be 1:3
In a geometric sequence the between consecutive terms is constant.?

What is the cylinder compression in foot pounds in a 1340 harley Davidson evolution engine?
Compression is normally expressed in terms of pounds per square inch (PSI),...foot lbs would relate to twisting forces such as a spinning crank shaft. Two different animals.
