• CTech Fuel Pump Circuit

    When the torque production of the engine surpasses the supply of the fuel pump, you upgrade to one with higher flow capacity.

  • IC Engine Kinematics

    The first in a three part discussion analyzing the kinematics of the lower rotating assembly of an internal combustion engine. Here we will model and plot the motion of the piston and consider numerical differentiation.

  • Knock Resistance in Turbocharged IC Petroleum Engines

    A look into the process of pre-ignition in turbocharged internal combustion engines, and ways to avoid it.

  • Mechanical Versus Electrical System Control

    The computer that controls the ignition and injection events in an IC engine works many thousand times faster. Here we look at how much control a modern processor has on a mechanical system.

  • Polishing Aluminum

  • Specific Fuel Consumption

    Engines work most efficiently at a certain operating point. Specific fuel consumption aids in analyzing the fuel economy and torque of an IC engine.

  • The Bigger Boost

    Lorem ipsum dolor sit amitExpha's first editorial on why a manual boost controller is inferior in operation to an electronic boost controller.

  • Valve flow, an intro

    An in-depth introduction to the flow of poppet valves in internal combustion engines. Also, Expha's first attempt at complex mathematical formulas in an article.

  • Welded center differential

    The center differential initiates the torque split between the front and rear differentials in the Getrag W5MG1 5-speed all-wheel-drive transmission.
