Automotive Engineering Diploma

Explore the basic engine, an internal combustion power unit that drives vehicle wheels, comparing gasoline spark-ignition and diesel compression-ignition designs, and detailing cylinder block, cylinder head, piston, and four-stroke operation.

Explore lubrication, cooling, fuel and air delivery, and emission control to keep engines running efficiently. Understand ignition systems, spark plugs, distributors, coils, and electronic control modules for precise timing.

Understand starting and charging systems from the battery and starter motor to the alternator and regulator, and examine electronic engine control, onboard diagnostics, heating and air conditioning refrigerant cycle.

Explore how the drivetrain transfers engine power to the wheels across rear, front, and four-wheel drive systems. Learn about clutch, manual and automatic transmissions, torque converter, drive line, and differentials.

Explore the running gear, including wheels, tires, suspension, steering, and brakes. Learn how springs, torsion bars, and shocks support the frame and how power-assisted steering and ABS enhance control.

Explore how hybrid electric vehicles use electric motors and an engine to propel and recharge batteries through a generator, with parallel and series designs and regenerative braking.

Explore the internal combustion automotive engine, including the cylinder block and head, valves, camshaft, pistons, and crankshaft. See how the four-stroke cycle and ignition convert piston motion to wheel power.

Explore various engine configurations, including inline, V type, W type, slant, and opposite-cylinder boxer designs, and compare front, mid, and rear engine placements and camshaft layouts.

Explore engine measurement and performance, including bore, stroke, and displacement; compare square, over-square, and under-square designs, and examine compression ratio with volumetric, mechanical, and thermal efficiency shaping torque and horsepower.

Diesel engines serve as the dominant power source for heavy trucks and equipment, using compression ignition, high compression ratios, and advanced fuel systems like common rail and direct injection.

Examine cylinder block, a precision casting that houses combustion parts and may be iron, aluminum, or magnesium, with liners, wet or dry sleeves, oil passages, cooling jackets, and two-piece designs.

Explore camshafts with lobes that open valves via lifters and rocker arms, synchronized to the crankshaft, and learn about belt, chain, and gear drives, cam profiles, lift, and overlap.

Explore crankshaft construction in cast iron, forged steel, or nodular iron, with main bearing journals, crankpin offsets, counterweights, oil clearance, torsional dampers, and flywheel function for smooth operation.

Explore crankshaft bearings, from full round and split insert designs to thrust bearings, detailing materials, silicone content, oil grooves, locating lugs, and oil flow for heat and wear management.

Transmit piston pressure to the crankshaft via the connecting rod. Seal the cylinder and manage oil with piston rings, supported by steel, aluminum, or titanium.

Explore how a positive displacement oil pump, driven by the crankshaft or camshaft, moves oil from the pan through filters and passages, with pressure regulated by a relief valve.

Explore the cylinder head's cast iron or aluminum construction, valves and ports, siamese and crossflow port designs, cooling and oil passages, head gasket, and camshaft supports.

Explore how combustion chamber shape, ignition position, and squish or quench areas influence turbulence, air-fuel mixing, and efficient combustion, covering wedge, hemispherical, and pent roof chamber designs.

Investigate intake and exhaust poppet valves, their materials, heat management, and basic valve terminology. Examine multi-valve engines and variable valve timing systems to improve efficiency and power.

Explore engine gasket types—from soft cut and paper fiber to molded rubber and hard gaskets—and their roles in sealing head, oil pan, valve cover, and manifold with adhesive sealants.

Explore the lubrication system and engine oil flow, from the sump and oil pump to filters, galleries, and coolers, ensuring proper lubrication, cooling, sealing, and contaminant removal.

Explore how cooling systems remove engine heat with coolant, radiator, thermostat, water pump, hoses, expansion tank, and cooling fans to maintain safe operating temperatures.
