ABSTRACT Camless internal combustion engines offer major improvements over traditional engines in terms of efficiency‚ maximum torque and power‚ pollutant emissions. Electromechanical valve actuators are very promising in this context‚ but still present significant control problems. Low valve seating velocity‚ small transition time for valve opening and closing‚ unavailability of position sensor are the main objectives to be considered in the design of the valve control system. Actuator physical

Wankel Rotary Engine: A History by John B. Hege Well Done Conceived in the 1930s‚ simplified and successfully tested in the 1950s‚ the darling of the automotive industry in the early 1970s‚ then all but abandoned before resurging for a brilliant run as a high-performance powerplant for Mazda‚ the Wankel rotary engine has long been an object of fascination and more than a little mystery. A remarkably simple design (yet understood by few)‚ it boasts compact size‚ light weight and nearly vibration-free

Koenigsegg’s New Cam-Less Engine February 13‚ 2012 by Matt Jalopnik reports on an upcoming supercar from Swedish boutique automaker Koenigsegg that will feature a twin-turbo V8 engine whole valves are actuated without camshafts. Partnering with Swedish engineering firm Cargine‚ Koenigsegg plans to develop a valvetrain system whereby the valves are operated using pneumatic pressure alone. F1 car engines have used pneumatic valve springs since the Renault turbo engines of the mid-’80s‚ but always

Competition Apex Seal Information Engine — Rotary Carbon apex seals and Iannetti Advanced Carbon seals are recommended for any engine that will see 8000 rpm and above. They weigh significantly less than the stock (cast iron) apex seals and provide lower mass‚ keeping the apex seal in contact with the rotor housing face at high rpm. At high rpm‚ the stock (cast iron) seal overcomes the spring‚ causing the seal to skip across the rotor housing surface‚ reducing engine performance. Cast iron seals

Revolution of Car Engines Introduction By definition an automobile or car is a wheeled vehicle that carries its own motor and transports passengers. The automobile as we know it was not invented in a single day by a single inventor. The history of the automobile reflects an evolution that took place worldwide. It is estimated that over 100‚000 patents created the modern automobile. You can point to the many firsts that occurred along the way to producing the modern car; and with that goal

As we know the modern car engine is works in the internal combustion so it is call internal combustion engines. But for the older technology‚ they used External Combustion Engines. It is far lower efficiency than internal combustion engines. The steam engine

Introduction to Engine Performance – Study Guide ©2005 Melior‚ Inc. ____________________________________________________________________________________ Introduction The engine is the power plant of a vehicle. Automotive engines have gone through tremendous changes since the automobile was first introduced in the 1880s‚ but all combustion engines still have three requirements that must be met to do their job of providing power – air‚ fuel‚ and ignition. The mixture of air and fuel must be compressed
