Like much in life, the difference between detonation and pre-ignition, and their effects, comes down to timing. Both refer to a situation when an engine's fuel/air mixture combusts at the wrong time, ...

In Part One of this series (January '93), we discussed how an internal-combustion engine heats a fuel-and-air mixture to convert it into mechanical energy. In February, we reviewed how a four ...

The intake manifold distributes air or air/fuel mixtures to the individual cylinders under varying engine speeds, loads, and environmental conditions. Whether the working flow is pure air, air/fuel, ...

Intake manifolds may not be the most well-known automotive components, but that doesn't take away from their importance. These devices are responsible for sending a precise mixture of fuel and air to ...

A research team in Japan and Romania has offered an alternative to conventional spark plugs, replacing them with durable lasers to ignite the fuel- air mixture that would lower consumption and raise ...

Internal combustion engines are a puzzle of mechanical wizardry designed to convert air and fuel into useable energy. They function by ingesting an air/fuel mixture into the cylinders—the mixture is ...
