GASOLINE DIRECT INJECTION

INTRODUCTION

For many years, innovative engine technology has been a development priority of Mitsubishi Motors. In particular, Mitsubishi has sought to improve engine efficiency in an endeavor to meet growing environmental demands, such as those for energy conservation and the reduction of CO2 emission to limit the negative impact of the green-house effect.

 

In Mitsubishis endeavor to design and build ever more efficient engines, it has devoted significant resources to developing a gasoline direct injection engine. For years, automotive engineers have believed this type of engine has the greatest potential to optimize fuel supply and combustion, which in turn can deliver better performance and lower fuel consumption. Until now, however, no one has successfully designed an in-cylinder direct injection engine for use on production vehicles. A result of Mitsubishis engine development capabilities, Mitsubishis advanced Gasoline Direct Injection GDI engine is the realization of engineering dream.

under water gliders

S Y N O P S I S

      Autonomous underwater gliders, and in particular autonomous underwater gliders, represent a rapidly maturing technology with a large cost-saving potential over current ocean sampling technologies for sustained(month at a time) real-time measurements.

     This report gives us an overview of the main building blocks of an underwater glider system for propulsion, control, communication and sensing. A typical glider operation, consisting of deployment, planning, monitoring and recovery will be described using the 2003 AOSN-II field experiment in Monterey Bay, California.

     We briefly describe recent developments at NRC_IOT, in particular the development of a laboratory-scale glider for dynamics and control research and the concept of a regional ocean observation system using underwater gliders.

ABSORPTION REFRIGERATION SYSTEM

ABSORPTION REFRIGERATION SYSTEM

USING ENGINE EXHAUST GAS
DOC FILE UPLOADED

ABSTRACT

This work presents an experimental study of an ammonia–water absorption refrigeration system using the exhaust of an internal combustion engine as energy source. The exhaust gas energy availability and the impact of the absorption refrigeration system on engine performance, exhaust emissions, and power economy are evaluated. A production automotive engine was tested in a bench test dynamometer, with the absorption refrigeration system adapted to the exhaust pipe. The engine was tested for 25%, 50%, 75% and wide-open throttle valve. The refrigerator reached a steady state temperature between 4 and 13 degree centigrade about 3 hours after system start up, depending on engine throttle valve opening. The calculated exhaust gas energy availability suggests the cooling capacity can be highly improved for a dedicated system. Exhaust hydrocarbon emissions were higher when the refrigeration system was installed in the engine exhaust, but carbon monoxide emissions were reduced, while carbon dioxide concentration remained practically unaltered.
