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.

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.

In 1907, a very fruitful co-operation with the Stockholm-based engineering company " Fritz Egnell " began, with a one-cylinder 3 hp compression ignition engine.

A tank of the T95 series, armed with a smoothbore cannon and powered by a compression ignition engine, was envisaged by the Army Staff as the bearer of the role of future MBT.
15.
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.
16.
Diesel s theoretical studies demonstrated potential thermal efficiencies for a compression ignition engine of 36 % ( compared with 6 10 % for steam ), and an 1897 one-cylinder prototype operated at a remarkable 26 % efficiency.

However, when weight and size are not an issue, the cycle's potential for high thermodynamic efficiency makes it ideal for diesel compression ignition engines operating in large, weight-insensitive applications, such as marine propulsion, electricity generation.
18.
A "'carbureted compression ignition model engine "', popularly known as a "'model diesel engine "', is a simple compression ignition engine made for model propulsion, usually model aircraft but also model boats.
19.
Although originally conceived as a compression ignition engine, by the time Rolls-Royce started serious development, in conjunction with the Ricardo company, the decision had been taken by the Air Ministry to revert to a more conventional spark-ignition layout, although still retaining fuel injection.
20.
Gasoline engines combine homogeneous charge ( HC ) with spark ignition ( SI ), abbreviated as HCSI . Diesel engines combine stratified charge ( SC ) with compression ignition ( CI ), abbreviated as SCCI . HCCI engines achieve gasoline engine-like emissions with compression ignition engine-like efficiency.
