Injection advancement for piston cooling in spark ignition direct injection engines |
摘要 |
An engine system comprises a temperature determination module, a temperature comparison module, and a fuel injection control module. The temperature determination module determines an engine temperature. The temperature comparison module compares the engine temperature and a temperature threshold. The fuel injection control module adjusts a timing of fuel injection from a first range of an intake stroke to a second range of the intake stroke based on the comparison. The first range and the second range do not overlap.
