Ultimate cooling system

Introduction to cooling systems

An engine provides mechanical energy from an air/fuel mixture with an efficiency between 20 and 45%. The rest flows in kinetic and heat energy in exhaust gases and in heat energy through metallic bodies due to the frictions. In this context, the cooling system must allow the engine to give its best performance, ensure the […]

NEDC

The different driving cycles

A driving cycle commonly represents a set of vehicle speed points versus time. It is used to assess fuel consumption and pollutants emissions of a vehicle in a normalized way, so that different vehicles can be compared. The driving cycle is performed on a chassis dynamometer, where tailpipes emissions of the vehicle are collected and

Introduction to internal combustion engine

The vehicle propulsion is usually obtained by means of engines, also known as prime movers, i.e. mechanical devices capable to convert the chemical energy of a fuel into mechanical energy. By the way, the English term “engine”, is likely to have a French origin in the Old French word “engin” which in turns is thought

Cordierite for catalytic converters

A cordierite perspective The cordierite is issued from sedimentary rocks. Deposits can be found in Sri Lanka, India, Burma, Madagascar, USA and Canada. It has a high thermal resistance and is a relatively strong material. However, it has a high coefficient of thermal expansion (CTE) and a relatively low density. Cordierite is a high volume

MIVEC 4B12 engine

The Mitsubishi Innovative Valve timing Electronic Control system (MIVEC) engine

Mitsubishi Motors has been focusing for a long time on technologies to controlled valve timing and amount of lift with the aim of achieving high power output, low fuel consumption, and low exhaust emission. The MIVEC engine was first used in 1992 in the Mirage, and since then they have been adding a number of
