technology Construction and Working The six stroke engine basically works just like a four stroke engine. The major difference is in the construction. The major drawbacks of conventional engines were poppet valves‚ its basic problems being and - inertia‚ inhibiting flow especially the exhaust valve hot-spot in the combustion chamber. So a six stroke engine was simplified with the objective of improving efficiency and increasing performance compared to a conventional engine by overcoming the drawbacks

VALVETRONIC ENGINE TECHNOLOGY 1. INTRODUCTION The automobile has been providing individual mobility for more than 100 years. This mobility is made possible first and foremost by combustion engines drawing their power from fossil energy carriers‚ which‚ even today‚ provide the foundation in generating mechanical drive power in the automobile. The primary objectives in developing drive systems are to curb fuel consumption and reduce CO2 emissions. In an effort to meet this challenge

and‚ in spite of various mechanical and hydraulic add-on devices like VIT‚ etc.‚ timing control possibilities are limited with mechanical cams. Not least fuel injection pressure control and variation over the load range have limitations with a camcontrolled engine. Therefore‚ the main purpose of changing to electronic control is to ensure fuel injection timing and rate‚ as well as the exhaust valve timing and operation‚ exactly when and as desired‚ see Fig. 2.

stream. It then would send a signal to a microprocessor‚ which would analyze the reading and operate a fuel mixture or air mixture device to create the proper air/fuel ratio. As computer systems progressed‚ they were able to adjust ignition spark timing as well as operate the other emission controls that were installed on the vehicle. The computer is also capable of monitoring and diagnosing itself. If a fault is seen‚ the computer will alert the vehicle operator by illuminating a malfunction indicator
