A homogeneous-charge, compression-ignition engine having engine coolant, an intake manifold and an exhaust manifold including a controller for advancing and retarding auto-ignition in the combustion chamber of the engine, the intake manifold providing a premixed combustible charge of air and fuel, the intake manifold having dual intake portions, one portion supplying unheated gas, and the other providing gas heated by engine coolant or exhaust gas, or both. A flow distributor valve in the intake manifold gas flow passages varies the intake temperature, thereby controlling auto-ignition timing and the combustion rate in the engine combustion chamber during the portion of the combustion cycle in which a homogeneous-charge, compression-ignition event occurs. The engine includes a spark ignition system for initiating combustion when the engine load, for a given speed, increases to a defined level and when the engine speed for a given load increases to a defined level.

[ What is claimed is:] [1.]1. A homogeneous-charge, compression-ignition engine system having a gas charge intake manifold and an exhaust gas manifold, an engine having a gas charge combustion chamber, a gas charge intake in the combustion chamber communicating with the intake manifold, and an exhaust port in the combustion chamber communicating with the exhaust manifold;means for recovering thermal energy of exhaust gas and for transferring it to the gas charge in the intake manifold; andmeans for adjusting the rate of heat transfer from the exhaust manifold to the combustion chamber whereby timing of auto-ignition of the air-fuel mixture in the combustion chamber is controlled during a combustion cycle.
