The Split Cycle Engine

The Split-Cycle Engine changes the heart of the conventional engine by dividing (or splitting) the four strokes of the Otto cycle over a paired combination of one compression cylinder and one power cylinder. Gas is compressed in the compression cylinder and transferred to the power cylinder through a gas passage. The gas passage includes a set of uniquely timed valves, which maintain a prechargedpressure through all four strokes of the cycle. Shortly after the piston in the power cylinder reaches…

The Day I First Rode a Go Kart

It was a good few weeks into the summer holidays of three years ago, and I was eleven years of age. I was with my family on a vacation in North Wales, situated right near the sunny beaches of a town called “Pwllheli”. That summer we had rented out a wooden lodge from a dear friend of my mothers and we couldn’t have been staying in a more beautiful place. Around the lodge were towering trees with the hot, glorious…

Gas Compressor

A gas compressor is a mechanical device that increases the pressure of a gas by reducing its volume. Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. As gases are compressible, the compressor also reduces the volume of a gas. Liquids are relatively incompressible, so the main action of a pump is to pressurize and transport liquids. Types of Compressors Centrifugal compressors Centrifugal compressors use a rotating disk…

Balancing of an Outboard Engine

Balancing of an engine involves designing, construction and tuning of the engine in order to ensure it runs efficiently. This minimizes stresses such as vibration hence improving its performance and reliability by reducing the maintenance costs and tolerating high working speeds. The smoothness is determined by the configuration of the engine (number of the cylinders as well as their arrangements) and can be achieved by strengthening the engine block, crank shaft etc. nd minimizing friction. “…no engine can be perfectly…

Force Induction Systems

Have you ever wanted to know how to make your car go faster? While I can make no guarantees that your car will be a qualifier for the next Fast and Furious movie, I can coach you on how to get the biggest bang for your buck, or in this case, speed from your engine. The simplest method for boosting speed is installing a force induction system that consists of either a turbocharger or a supercharger. Most turbochargers and superchargers…

Turboprop Engines

Turboprop engines are a type of aircraft powerplant that use a gas turbine to drive a propeller. The gas turbine is designed specifically for this application, with almost all of its output being used to drive the propeller. The engine’s exhaust gases contain little energy compared to a jet engine and play a minor role in the propulsion of the aircraft. The propeller is coupled to the turbine through a reduction gear that converts the high RPM, low torque output…
