One Thing we've discovered about the OHC modular motors is that they are highly sensitive to cam timing. Unfortunately, the production tolerances are such that the cam timing can be off significantly ...

At the risk of losing credibility with our readers (assuming I had any to begin with!), I must admit to never having built an engine before. I've done general maintenance, bodywork, welding, complete ...

This diagram shows the major cam events through one full cylinder cycle (two crank revolutions or 720 degrees), beginning at TDC firing. The exhaust lobe and valvetrain is closer to the front, and ...

A cam phaser is a sprocket which adjusts the position of an engine’s camshaft in relation to its crankshaft and is tuned with a computer-controlled servo. Camshafts control the timing of engine intake ...

The hunt for efficient engine valve technology can be a never-ending journey into cam timing, various combustion cycles, and lift and duration adjustments. For that reason, some companies believe ...

BorgWarner has patented a variable cam timing phaser with a lock pin that acts as a shutoff valve, preventing oil leakage from advance and retard chambers. This innovation maintains oil in the phaser ...

We must first understand what each of these two systems does for a car. They both serve the same purpose, which is to coordinate the movement of the crankshaft as well as the camshaft(s) so that the ...

BorgWarner has announced a deal to supply variable cam timing (VCT) and engine timing systems for Jaguar Land Rover’s new Ingenium I4 engine line. Based on a configurable and flexible architecture to ...
