Common engines direct an oil spray on the underside of the piston to carry away the heat generated at high power levels. The 2000 features cast-in channels in the pistons through which high pressure oil is accurately directed, ensuring proper cooling and significantly reduced piston temperatures. The result is long life, even at prolonged high speeds during a lengthy cruise. Smoke is often unavoidable with common engines. Either black smoke at cruising speed or with smoke at start-up, sometimes both.
Smoke is bothersome and often embarrassing.
Builders of common engines are always searching for one solution. The Series 2000 offers many. The engine idles on only half the cylinders when cold. This technique places enough load on those cylinders to ensure rapid warm up. Once warm, the other cylinders are automatically added without embarrassing smoke.
