A multi-mode internal combustion engine and method of operating the engine is provided which is capable of operating in a variety of modes based on engine operating conditions to enhance fuel efficiency and reduce emissions. The multi-mode engine include a fuel delivery system and control system for permitting the engine to operate in a diesel mode, a homogeneous charge dual fuel transition mode, a spark ignition or liquid spark ignition mode and/or a premixed charge compression ignition mode. The control system and method permits the engine operation to transfer between the various modes in an effective and efficient manner by controlling one or more fuel delivery devices or other engine components so as to move along a continuous transfer path while maintaining engine torque at a substantially constant level.

A device as defined in claim 12, wherein said learn controller is set to disregard a manual start that occurs less than a minimum time period of 20 minutes following an engine shutdown in order to calculate K. 14. A device as defined in claim 7, further comprising a temperature sensor, and a plurality of K values stored in said storage device, each K value corresponding to a range of temperatures, said temperature sensor sensing the outside temperature and said remote start controller using the K value appropriate for said outside temperature. 15. A device as defined in claim 7, wherein said remote car starter responds to a start command signal, said start signal is received through a transceiver. 16. A device as defined in claim 7, wherein said learn controller calculates a minimum starter motor activation time Tm,defined as the total starter motor activation time minus an average operator response time Tdeltaseconds, within a minimum value of 475 ms and a maximum value of 3 seconds, said remote start controller automatically cutting off said starter motor after Tmseconds, regardless of whether said engine has started or not. 17. A device as defined in claim 7, wherein Tdeltais approximately 200 ms and corresponds to the average operator response time. 18. A device as defined in claim 7, further comprising a temperature sensor, said temperature sensor capable of determining if the engine is of appropriate temperature to enter a learn mode and calculate K, whereby K is not calculated if the engine is warm. r is defined between the partition plate and a partition body welded thereto. It is thus possible to form the oil recovery chamber and the breather chamber without splitting the roof of the head cover, thereby making inspection of the joint for oil tightness unnecessary.
