1. Wilksch engines are compression ignition engines which burn Diesel fuel or jet fuel. 2. Stratified charge compression ignition also relies on temperature and density increase resulting from compression. 3. Diesel, i . e . compression ignition engines are used. 4. Compared with steam, petrol and compression ignition engines, hot-bulb engines are simpler, and therefore have fewer potential problems. 5. Compression ignition Diesel engines ignite the fuel-air mixture by the heat of compression and do not need a spark.6. Rotaries generally have high compression ratios leaning the design to ease of homogeneous charge compression ignition ( HCCI ) adoption. 7. The engine passed the 50-hour civil type test for compression ignition engines, being only the second British engine to do so. 8. When running at lower speeds, quenching is commonly observed in diesel ( compression ignition ) engines that run on natural gas. 9. These motors are compression ignition , so there are no ignition timing issues and little difference between running forward and running backward. 10. There's a growing usage of renewable fuels like biodiesel for compression ignition engines and bioethanol or methanol for spark ignition engines.
