Cylinder head porting — refers to the process of modifying the intake and exhaust ports of an internal combustion engine to improve the quality and quantity of the air flow. Cylinder heads, as manufactured, are usually suboptimal due to design and manufacturing… … Wikipedia
Cylinder head — A 302/5.0L Ford cylinder head In an internal combustion engine, the cylinder head (often informally abbreviated to just head) sits above the cylinders on top of the cylinder block. It closes in the top of the cylinder, forming the combustion… … Wikipedia
Cylinder (engine) — Illustration of an engine cylinder with a cross section view of the piston, connecting rod, valves and spark plug. A cylinder is the central working part of a reciprocating engine or pump, the space in which a piston travels. Multiple cylinders… … Wikipedia
Volumetric efficiency — in internal combustion engine design refers to the efficiency with which the engine can move the charge into and out of the cylinders. More correctly, volumetric efficiency is a ratio (or percentage) of what volume of fuel and air actually enters … Wikipedia
Engine efficiency — of thermal engines is the relationship between the total energy contained in the fuel, and the amount of energy used to perform useful work. There are two classifications of thermal engines (1) Internal combustion (gasoline, diesel and gas… … Wikipedia
Reverse-flow cylinder head — A reverse flow or non crossflow cylinder head is one that locates the intake and exhaust ports on the same side of the engine. The gases can be thought to enter the cylinder head and then change direction in order to exit the head. This is in… … Wikipedia
Fuel efficiency — is a form of thermal efficiency, meaning the efficiency of a process that converts chemical potential energy contained in a carrier fuel into kinetic energy or work. Overall fuel efficiency may vary per device, which in turn may vary per… … Wikipedia
Revolving cylinder engine — The primary claimed benefit of the revolving cylinder, axial piston engine is that a 4 cycle, reciprocating piston engine can be achieved without the need for a complex and expensive valve train. The intake and exhaust flows are controlled by… … Wikipedia
Office of Energy Efficiency — Natural Resources Canada s Office of Energy Efficiency provides advice and financial assistance including grants to individuals and organizations to reduce energy use.The ecoENERGY for Personal Vehicles program maintains fuel economy information… … Wikipedia
charging efficiency — [1] In a vehicle s electrical charging system, its efficiency is the ratio of energy output to energy input, i.e., how well does the alternator work to supply voltage to the electrical components and still charge the battery. [2] In a two stroke… … Dictionary of automotive terms
volumetric efficiency — [1] A comparison between the actual volume of fuel mixture drawn in on the intake stroke and what would be drawn in if the cylinder were to be completely filled. In practice, a normally aspirated car engine does not take in an amount of an equal… … Dictionary of automotive terms
