This single piston GDI High Pressure Fuel Pump is suitable for most homogeneous and stratified combustion gasoline direct injection engine schemes. Its roller follower or tappet cam drive plunger designs reduce friction and contribute to fuel economy and greater power. The pump is an engine driven, on-demand control pump that features a single-piston and integrated design, also supporting a wide range of engine software maps. It delivers operating pressure from 30 bar to 200 bar, or 100 to 2900 PSI. These pumps offer a high flow capability for larger displacement engines. GDi Fuel Pumps includes an integrated flow control valve for accurate fuel control and an integrated overpressure relief valve. A one way valve is also included, which helps maintain the fuel rail internal pressure. Seen here we can see the cam lobe actuating on the GDI high pressure pump plunger and piston. Upon simple observation it is a normal piston pump, with nothing extraordinary about it. However, the key component here is the fuel pressure control solenoid to the right of the pump side. The ingenious ingredient here is the high processing power of the ECM used to control the pump solenoid. The idea is for the ECM to .... Get the whole story right here in this video... Enjoy...

Nissan GT-R Engine Assembly
Here are some quick scenes from the Nissan Yokohama engine plant's Clean Room. It takes an average of 100 minutes for an engine master to assemble one engine. Each man diligently checks and records the torque spec of every critical nut and bolt, and the data is stored for the life of the engine.





How modern technology can increase horsepower and gas mileage at the same time.
Emmy Award winning mechanic Scotty Kilmer shows how Fords new ecoBoost gasoline direct injection system can increase horsepower and get better gas mileage at the same time. The trick is high pressure direct injection into the engine cylinders.And, If you like my car help, be sure to watch my live car talk show every Saturday morning at 10 AM CST on YouTube.

Fuel Trim (SFT/LFT) vs. O2S B1S2
Me and my friends (Colleagues) repeatedly faced with the fact that the faulty O2S B1S2 (downstream Oxygen Sensor) was the cause of the DTC P0171 on Lexus RX300 2001MY. This video (Russian with English Subtitles) shows some of the checking ECM parameters with faulty probe ( O2S B1S2), by using the "downsream O2S simulator", before and after installing a new O2S B1S2, and the results of the active test "A/F Control" by Toyota Techstream.
