    摘要： A two cycle internal combustion engine is provided having a decompression slot (56) in order to ease engine starting. The engine utilizes a transfer port induction system in which a transfer port (40) is formed in the wall of the cylinder assembly in communication with the enclosed crank case (44) cavity. Extending from the top of the generally diametrically opposed transfer ports (40) are a pair of recessed decompression slots (56) extending from the upper most end of the transfer port (40) toward the closed end of the cylindrical cavity formed in the cylinder assembly (20). Each of the decompression slots (56) have a circumferential width W which is substantially constant. The radial of dimension D varies generally linearly from a maximum depth at the intersection of decompression slot (56) and transfer port (40) to a minimum depth at the uppermost end of the decompression slot (56).

    摘要： An engine includes an intake, an air-fuel path coupled to the intake, an accumulator configured coupled to the air-fuel path and configured to store an air-fuel mixture, and at least one valve configured to selectively provide the air-fuel mixture from the engine to the accumulator at a first time and store the air-fuel mixture within the accumulator at a second time. A controller may be configured to provide commands to the at least one valve. The plurality of commands may include an open command to release air and fuel mixture from the accumulator and a close command to store air and fuel mixture in the accumulator.

    摘要： When a request for re-start of an engine or a request for start occurs during inertial revolution of the engine by fuel cut at the time of request for idle stop, an operation of starting by re-start of fuel injection and an operation of driving the starter overlap, and a problem is likely to occur in wear resistance and durability of a ring gear 106 and a pinion gear 101e. Further, since collision torque becomes large, a collision sound of the ring gear 106 and the pinion gear 101e and a mesh sound which occurs at the instant of connection are likely to occur. The present invention changes a method of starter drive based on a behavior of engine revolution after a request for re-start of the engine or a request for start occurs during inertial revolution of the engine by fuel cut at the time of request for idle stop, and combustion recovery is implemented by an engine combustion recovery function 103d, or an engine state or the like at the time of occurrence of change of mind, in a controller 103 of a vehicle having an idle stop function.
