solid injection 예문

• With much higher pressures and high technology injectors, present-day diesel engines use the so-called solid injection system applied by Herbert Akroyd Stuart for his hot bulb engine.
• They had the advantage of comparative simplicity, since they did not require the air compressor used by early Diesel engines; fuel was injected mechanically ( solid injection ) near the start of the compression stroke, at a much lower pressure than that of Diesel engines.
