OIL PUMP: TYPES, DRIVE MECHANISM, ELECTRONIC OIL PUMP
March 10, 2020 Mechanical Engineering FAHADH V HASSAN

The oil pump is the heart of the lubrication system. It sucks oil up from the oil pan and forces it around oilways in the engine before the oil drops back into the sump and is recirculated. The oil pump is a highly critical part of the engine – if

DISTRIBUTORLESS IGNITION SYSTEM / DIS /: COMPONENTS, WORKING PRINCIPLES, AND TYPES
March 10, 2020 Mechanical Engineering FAHADH V HASSAN

Distributorless Ignition System (DIS) is the ignition system in which the distributor of the electronic ignition system is replaced with number of induction coils i.e. one coil per cylinder or one coil for pair of cylinders, and the timing of the spark is controlled by an Ignition control unit (ICU)

ENGINE LUBRICATION SYSTEM: WORKING PRINCIPLE, COMPONENTS, AND IMPORTANCE
March 10, 2020 Mechanical Engineering FAHADH V HASSAN

When two metallic surfaces under direct contact move over each other, they create friction which generates heat. This causes excessive wear and tear of those moving parts. However, when a film of lubricating matter separates them from each other, they do not come in physical contact with each other. Thus,

ELECTRIC PARKING BRAKE (EPB): COMPONENTS, WORKING PRINCIPLE, AND TYPES
March 10, 2020 Mechanical Engineering FAHADH V HASSAN

The Electric Park Brake functions as a conventional hydraulic brake for standard service brake applications, and as an electric brake for parking and emergency braking. Electric Park Brake (EPB) is a caliper with an additional motor (motor on the caliper) that operates the parking brake. The EPB system is electronically

EXHAUST GAS RECIRCULATION (EGR) SYSTEM: WORKING PRINCIPLE, DESIGN, AND BENEFITS
March 10, 2020 Mechanical Engineering FAHADH V HASSAN

Diesel engines tend to emit higher Nitrogen Oxide (NOx) which is harmful to humans. This is because of the high temperatures in the engine cylinders because of the higher compression ratio. To control and decrease the NOx, manufacturers employ ‘Exhaust Gas Recirculation’ technology in engines. The term EGR stands for

SI VS CI ENGINES: DIESEL VS GASOLINE ENGINE
March 6, 2020 Mechanical Engineering FAHADH V HASSAN

SI VS CI ENGINES: DIESEL VS GASOLINE ENGINE An engine is a machine that converts some form of energy into mechanical work. Internal combustion engines can be divided according to several characteristics. Depending on the creating of the mixture and the ignition (the thermodynamic process), engines are divided into Otto
