A wastegate is a valve that controls the flow of exhaust gases to the turbine wheel in a turbocharged engine system. [1] Diversion of exhaust gases regulates the turbine speed, which in turn regulates the rotating speed of the compressor. The primary function of the wastegate is to regulate the maximum boost pressure in turbocharger systems, to ...
There was no direct indication of the valve's actual position. A light on a control panel, installed after the PORV had stuck open during startup testing, [37] came on when the PORV opened. [38] When that light—labeled Light on – RC-RV2 open [39] —went out, the operators believed that the
Ford EcoBoost engine. I3 1.5: Bosch MG1CS016 with CAN-Bus and individual cylinder knock control. FGEC software. EcoBoost is a series of turbocharged, direct-injection gasoline engines produced by Ford and originally co-developed by FEV Inc. (now FEV North America Inc.). [6] EcoBoost engines are designed to deliver power and torque consistent ...
The turbocharger was made by the Thompson Valve Division of Thompson-Ramo-Wooldridge Inc., which became TRW in 1965. [24] The model selected weighed 13.5 lb (6.1 kg). [22] It had a 3 in (76 mm) diameter impeller and was capable of spinning at up to 70,000 rpm. [25] The turbocharged Corvair engine did not use a wastegate to limit boost pressure.
Variable-geometry turbochargers (VGTs), occasionally known as variable-nozzle turbochargers (VNTs), are a type of turbochargers, usually designed to allow the effective aspect ratio (A/R ratio) of the turbocharger to be altered as conditions change. This is done with the use of adjustable vanes located inside the turbine housing between the ...
The GM L3B engine is a turbocharged four-cylinder gasoline engine designed by General Motors. It is an undersquare aluminum DOHC inline-four displacing 2.7 liters (165 cid) and tuned for strong low-end torque. In addition to GM's active fuel management, start-stop system, and variable valve timing, which are already featured on GM's other full ...
A poppet valve (also sometimes called mushroom valve[1]) is a valve typically used to control the timing and quantity of petrol (gas) or vapour flow into or out of an engine, but with many other applications. It consists of a hole or open-ended chamber, usually round or oval in cross-section, and a plug, usually a disk shape on the end of a ...
OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool.. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.
