End-of-life vehicles (ELV) policy implementation has long been a hotly debated issue in Malaysia. Vehicles that have become ELVs should be disposed of accordingly to prevent environmental pollution and also for the purpose recycling useful materials, particularly metals. The automotive industry affects earth environment through greenhouse gas emissions such as air-conditioning (CFC/HFC) which will increase global warming uncontrolled use raw materials. Even poorly managed ELV waste cause...

The elimination of NOx emissions for hydrogen combustion in the compression ignition (CI) engine is primary concern, therefore replacing nitrogen with noble gas one solutions to eliminated emission. Current research trend focuses on oxygen-argon as most suitable working. When using argon, external heating intake required low ratio (CR) engines. Hence, neon another potential solution because it has a high specific heat that other gasses capacity, Cp, which almost identical nitrogen. This...
