  • Patent number: 7703438
    Abstract: A method of maintaining homogeneous charge compression ignition when a temperature within a combustion chamber decreases below an autoignition temperature in an engine that is configured for homogeneous charge compression ignition under at least some engine operating conditions and for spark ignition under at least some engine operating conditions, the method comprising selectively heating contents of the combustion chamber with a glow plug.
    Type: Grant

  • Patent number: 7573219
    Abstract: A method and apparatus is disclosed for detecting whether belt slip is occurring between an electric machine and a machine drivingly connected together by a drive belt using only measurements of rotor speed, voltage and current derived from the electric machine, thereby improving the sensitivity of slip detection and eliminating the need for a comparison of rotor speed with a measurement of the rotational speed of the machine.

  • Publication number: 20050113211
    Abstract: A locking mechanism (6) is provided to block the internal combustion engine (1) at prepositioned cranking angle after shutting down. Preferably, the crankshaft of the engine is positioned at a crankshaft angle that is favorable for cranking. Prepositioning of the crankshaft angle results in a lower first compression torque and therefore increases kinetic energy stored in the crankshaft lumped inertia. The required maximum torque of the cranking aid (2a, 2b, 2c) can therefore be reduced.
