Abstract
A method of operating a vehicle including an engine includes suspending operation of the engine during operation of the vehicle including stopping fueling of the engine. The method includes accelerating the engine to a high-speed starting speed with fueling of the engine stopped and a cylinder decompression mechanism activated, the high-speed starting speed being greater than an idle speed of the engine. The method includes resuming operation of the engine including deactivating the cylinder decompression mechanism at the high-speed starting speed and thereafter restarting fueling of the engine.
Claims24
A method of operating a vehicle including an engine, the method comprising:
- operating an electronic control system to perform acts of:
- suspending operation of the engine during operation of the vehicle including stopping fueling of the engine,
- accelerating the engine to a high-speed starting speed with fueling of the engine stopped and a cylinder decompression mechanism activated, the high-speed starting speed being greater than an idle speed of the engine, and
- resuming operation of the engine including deactivating the cylinder decompression mechanism at the high-speed starting speed and thereafter restarting fueling of the engine.
A system comprising:
- a vehicle including an engine and an electronic control system, the electronic control system being configured to:
- suspend operation of the engine during operation of the vehicle including stopping fueling of the engine,
- accelerate the engine to a high-speed starting speed with fueling of the engine stopped and a cylinder decompression mechanism activated, the high-speed starting speed being greater than an idle speed of the engine, and
- resume operation of the engine including deactivating the cylinder decompression mechanism at the high-speed starting speed and thereafter restarting fueling of the engine.
An apparatus comprising:
- a non-transitory memory medium configured to store instructions executable by a processor to perform acts of:
- suspending operation of an engine during operation of a vehicle including stopping fueling of the engine,
- accelerating the engine to a high-speed starting speed with fueling of the engine stopped and a cylinder decompression mechanism activated, the high-speed starting speed being greater than an idle speed of the engine, and
- resuming operation of the engine including deactivating the cylinder decompression mechanism at the high-speed starting speed and thereafter restarting fueling of the engine.
