Automotive Engineering: Automobile Systems and Components

Explore air induction and fuel induction systems, including air filtration and turbocharged or supercharged pressurization for power. Calibrate air-to-fuel ratios to minimize inefficiencies, emissions, and engine damage.

Explore automotive air intake system from the intake grille and air filter to the throttle body and intake manifold, and learn how clean air boosts combustion, power, and fuel efficiency.

Explore how the throttle body uses a butterfly valve and throttle position sensor, controlled by the ECU and pedal input, to regulate air into the intake manifold for optimal combustion.

Discover how fuel travels from the tank through lines to the engine, powered by an in-tank electric pump and regulated pressure for injectors, with filters ensuring clean fuel.

Explore the fuel induction system, including the accumulator, return pipe, distributor, cold start injector, injectors, and how they maintain balanced fueling for the engine.

Boost engine power and efficiency by using a turbocharger to force compressed air into the combustion chamber, with a turbine driven by exhaust gases, a connected compressor, and an intercooler.

Explore the engine control unit (ECU) and its role in real-time fuel and air management through key sensors like MAF, IAT, TPS, MAP, and O2, plus drive-by-wire implications.

Examine the automotive electrical system: the battery as the main power source, the alternator recharging it while the engine runs, and the starter turning the engine.

explore how chassis grounding provides a safe reference and reduces wiring complexity, then examine wires, connectors, fuses, relays, and solid state options in automotive systems.

Discover how automotive power starts with the alternator creating AC, then a rectifier and capacitor convert it to stable DC to charge the battery and power the ECU.

Explore how the exhaust system routes combustion byproducts, including carbon monoxide and nitrogen oxides, from the engine through the manifold, catalytic converter, muffler, and tailpipe to reduce emissions and noise.

Explore how the exhaust manifold collects gases from cylinders and feeds the exhaust system, and how the catalytic converter uses a platinum-palladium-rhodium honeycomb to reduce NOx and hydrocarbons.

Explore exhaust system components, mufflers, resonators, and pipes, and learn how muffler designs reduce noise, how resonators target specific frequencies, and why materials like stainless steel and aluminium matter.

Drive learners to understand the cooling system: coolant flow from expansion tank through the water pump and engine jacket to the radiator and the thermostat, preventing overheating.

Explore the engine water jacket and cooling system components, including the centrifugal coolant pump and hoses, to circulate coolant, transfer heat to the radiator, and prevent hotspots.

Explore how the radiator, thermostat, expansion tank, and heater regulate engine temperature by circulating coolant, controlling pressure, and cooling with fan-assisted airflow.

Discover how a car's lubrication system delivers oil from the pan to engine bearings that support the crankshaft and camshaft through the pump, filter, galleries, jets, and relief valve.

Learn how the oil pan stores oil and protects the crank area, while oil pumps circulate lubricant through external, internal, and micro analog gear pumps and filters that remove contaminants.

Explore how the lubrication system delivers oil through galleries to main and rod bearings, supports camshaft lubrication by splash, and uses the oil ring to control film thickness and wear.
