Oil jets located in the block are employed for performance and temperature control. (cheersandgears.com)
To that end, a cylinder block rapid warm - up system suppresses the flow of coolant into the block when the engine is cold, and a piston cooling oil jet control system cuts the supply of oil to the pistons to improve warm - up speeds. (cheersandgears.com)
Improved cylinder block and head cooling, piston oil jet cooling and an optimized taper squish shape improve anti-knock performance, realizing a high compression ratio of 12.8:1. (greencarcongress.com)
