  • Internal combustion engine with five valves per cylinder

    The invention claimed is: 1. An Otto cycle internal combustion engine, comprising: a cylinder block including at least one cylinder having a longitudinal axis, a piston movable within said cylinder and having a recess open on a head surface of the piston, a head fastened to said cylinder block and having a surface facing said cylinder, three intake valves and two exhaust valves movable along

  • Otto Standard Cycle, gasoline engine operation. The | Chegg.com

    Otto Standard Cycle, gasoline engine operation. The Otto Cycle is an idealized thermodynamic cycle that is used to model the actual thermodynamic cycle under which internal combustion engines run on gasoline and spark plug sparks. It consists of 6 thermodynamic processes, of which only 4 involve movement of the cylinder piston in which internal.

  • How Do Car Engines Work?

    The combustion takes place in a metal cylinder, into which a cylinder slides and retreats. The movement of the piston reduces the available volume in the cylinder for gases, which is essential for the function of the engine. It is the change in pressure as the piston moves and then by the expansion of the gases, that is what drives the engine.

  • Testing Vapor Pressure of Polyol and Blowing Agents

    The GRABNER INSTRUMENTS vapor pressure tester MINIVAP VPXpert and a Floating Piston Cylinder (FPC) is used to test polyurethane blends. 1. The polyol blend is mixed with the proper blowing agent (e.g. n-pentane or cylcopentane) 2. The sample is mixed vigorously to form a homogenous mixture 3.

A compressed fuel charge is fired each time the piston reaches the top of the cylinder, and each downward stroke is a power stroke. In order to accomplish this, the initial

    An internal combustion engine, especially an Otto engine, with intake valves and with a fuel injector, which is arranged and designed so that it injects the fuel directly into a combustion chamber of working cylinders of the internal combustion engine.

  • Piston Engine Basics

    In the Otto-cycle scheme, there are four distinct cycles, differentiated by strokes of the piston inside the cylinder. On the first stroke, the piston moves downward, drawing fuel and air through a homeowner's nightmare of plumbing to the combustion chamber inside the cylinder. The second stroke sees the piston rising in the bore, compressing

  • Otto Cycle Engine

    The Otto cycle engine employs a spark to ignite a mixture of air and, traditionally, gasoline2 compressed by the piston within the engine cylinder. This spark ignition causes an explosive release of heat energy that increases the gas pressure in the cylinder, forcing the piston outwards as the gas tries to expand.

  • US6035637A

    This invention is an efficient free-piston internal-combustion engine having an expansion ratio greater than the compression ratio and preferably with gas bearings supporting the piston. The use of gas bearings in combination with high-temperature ceramic materials allows the engine to be nearly adiabatic and with exhaust temperatures in excess

  • History of the internal combustion engine

    1860: Jean Joseph Etienne Lenoir invented a gas-fired internal combustion engine, and applied for a patent titled Moteur à air dilaté par combustion des gaz.His engine is similar in appearance to a horizontal double-acting steam engine, with cylinders, pistons, connecting rods, and flywheel in which the gas essentially took the place of the steam.

  • US7958732B2

    A reciprocating engine, a piston engine, converts heat to mechanical energy. One or more pistons convert pressure into a rotating motion. A fuel-air mixture is introduced and ignited inside a cylinder, which houses a piston. Upon ignition, the hot gases expand, pushing the piston to the bottom of the cylinder.

  • Gunther, Christine and Otto

    As a result, even after nearly 900,000km Otto still did not consume oil, the engine cylinders had never needed re-lining and the pistons had never been replaced. They were inspected once, in 2004
