A compression ignition version of the Typhoon was projected and was the original choice of powerplant for the R101 airship, but this version proved impractical.

Hot bulb engines were produced until the late 1920s, often being called " semi-diesels ", even though they were not as efficient as compression ignition engines.
23.
The alternative was to introduce a tank from the T95 series, but it remained highly experimental with its compression ignition engine not as developed as the AVDS-1790.
24.
Homogeneous charge compression ignition ( HCCI ) is where the fuel / air intake is a pre-mixed lean air-fuel mixture then compressed to the point of auto-ignition.
25.
From the 1910s to the 1950s, hot-bulb engines were more economical to manufacture with their low-pressure crude-fuel injection and lower compression ratio than Diesel's compression ignition engines.
26.
Compression ignition or diesel engines were first used about 1910 for smaller sternwheel towboats, but did not gain ascendancy until the late 1930s, when diesel-powered propeller boats appeared.
27.
All diesel engines use compression ignition, a process by which fuel is injected after the air is compressed in the combustion chamber, thereby causing the fuel to self-ignite.
28.
They proposed that the most important improvements, better firepower and fuel economy, could be achieved by mounting a compression ignition engine and a more powerful gun on the M48A2.
29.
Compression ignition is demonstrated by placing a matchhead or other piece of tinder at the bottom of the fire syringe and then plunging the piston forcefully into the cylinder.
30.
On the other hand, Diesel engines operate on the principle of compression ignition, so that a fuel which resists autoignition will cause late ignition, which will also lead to engine knock.
