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

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.

### 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.
