text: However, the Hornsby-Akroyd oil engine and other hot-bulb engines are distinctly different from Rudolf Diesel's design, where ignition occurs through the heat of compression alone: An oil engine will have a compression ratio between 3:1 and 5:1, where a typical diesel engine will have a much higher compression ratio usually between 15:1 and 20:1, making it more efficient.
