RICE MACTRICE MACT

A A stationary reciprocating internal stationary reciprocating internal combustion engine (combustion engine (RICE) RICE) uses reciprocating uses reciprocating motion to convert heat energy into mechanical motion to convert heat energy into mechanical

work and is not mobile. A stationary RICE work and is not mobile. A stationary RICE differs from a mobile RICE since it is not a nondiffers from a mobile RICE since it is not a non--

fueled engine, or any other type of engine with a spark fueled engine, or any other type of engine with a spark plug (or other sparking device) and with operating plug (or other sparking device) and with operating characteristics significantly similar to the theoretical Otto characteristics significantly similar to the theoretical Otto combustion cycle. Spark ignition engines usually use a combustion cycle. Spark ignition engines usually use a throttle to regulate intake air flow to control power throttle to regulate intake air flow to control power during normal operation. Dualduring normal operation. Dual--fuel engines in which a fuel engines in which a liquid fuel (typically diesel fuel) is used for chlorine and liquid fuel (typically diesel fuel) is used for chlorine and gaseous fuel (typically natural gas) is used as the gaseous fuel (typically natural gas) is used as the primary fuel, at an annual average ratio of less than 2 primary fuel, at an annual average ratio of less than 2 parts diesel fuel to 100 parts total fuel on an energy parts diesel fuel to 100 parts total fuel on an energy equivalent basis, are spark ignition engines.equivalent basis, are spark ignition engines.
