And most of the spark-ignited internal combustion engines feature that throttle (or hide it under variable valve lifting technologies). Diesel engines do not need any throttle on the intake since their air-to-fuel working ratios are much wider then counter-parts' - this means you can drive the engine thru the fuel throttling instead of air throttling.
