Abstract: A method for cold engine starting in a pedal-start vehicle that comprises determining an ICE temperature value of an internal combustion engine of the vehicle upon starting the engine via depression of an accelerator, then comparing the ICE temperature value to a predetermined ICE temperature threshold value. Thereafter, when the ICE temperature value is below a predetermined ICE threshold value, controlling operation of the engine such that an RPM of the internal combustion engine remains within a predetermined idle RPM range for a predetermined amount of time, regardless of throttle control commands from the accelerator pedal of the vehicle, or when the ICE temperature value is equal to or greater than the predetermined ICE threshold value, or controlling operation of the internal combustion engine in accordance with the throttle control commands from the accelerator pedal.

Abstract: A vehicle transaxle comprising a plurality of mounting flanges fixedly mountable to an axle tube of the vehicle absent any additional structure for mounting the transaxle to the vehicle. The axle tube houses a wheel axle to which the transaxle is operably couplable. The transaxle additionally comprises a transaxle mounting collar that is fixedly mounted to or integrally formed with a housing of the transaxle. The mounting collar is structured and operable to have a prime mover of the vehicle mounted thereto and to support the weight/mass of the prime mover such that the prime mover is mountable to the vehicle via only the mounting collar absent any additional structure for mounting the prime mover to the vehicle such that the prime mover can be cantilevered from (e.g., suspended from) the transaxle, e.g., the prime mover is ‘free floating’.

Abstract: A prime mover for a lightweight vehicle comprising an internal combustion engine, a starter motor integrally integrated with the internal combustion engine, and a housing for the prime mover. The prime mover additionally comprises a Hall Effect sensor and an prime mover control module structured and operable to communicate with the Hall Effect sensor, determine when operation of the internal combustion engine should cease, and upon the determination that operation of the internal combustion engine should cease, utilize the communication from the Hall Effect sensor to stop the internal combustion engine such that a piston of the internal combustion engine is positioned at between 15° and 25° after bottom-dead-center.
