Have you noticed that some vehicles on the road have a 'T' following the engine displacement figure in their model designation? This actually indicates that the vehicle's engine is fitted with a turbocharger. This device increases engine output power during high-speed driving whilst offering relative fuel efficiency. The intake and exhaust intercooling system for automotive engines equipped with t...
Audi will unveil the facelifted A6 (available as a saloon and estate) at the Paris Motor Show this October, alongside the all-new high-performance RS6 variant. The updated models feature more fuel-efficient engines, retuned suspension systems, newly developed safety equipment, and the latest generation MMI multimedia interface. The signature Audi grille receives subtle refi...
Recently, BMW ALPINA, the exclusive independent brand under the BMW Group, officially unveiled its new brand emblem. This marks another significant milestone following the brand's formal debut as an independent entity within the BMW Group in January 2026. Paired with the previously revealed brand wordmark, the new emblem establishes BMW ALPINA's contemporary visual identity system. The brand's cor...
I. Composition of the Air Conditioning System & Introduction to Components Composition of the Air Conditioning System: Automotive air conditioning systems typically comprise the following components: compressor, condenser, receiver-drier, expansion valve, evaporator, blower fan, throttle valve, and ventilation system. Introduction to Air Conditioning System Components—HVAC Air Conditioning Ass...
Adding a turbocharger kit to your vehicle is a complex and intricate process. Forced induction conversion (adding a turbocharger or supercharger) should be undertaken with meticulous care and a thorough understanding of the concepts required for the system to function smoothly. Below is an explanation of the fundamental components that should be included in any basic turbocharger kit and their res...
How does a turbocharger work? Turbocharging works by compressing air, enabling the engine to accommodate greater volumes of air. This facilitates thorough mixing and combustion of fuel and air, thereby enhancing the engine's power output. What are the advantages and disadvantages of turbocharging? The advantages include an engine power increase of over 30%, with theoretically more complete combust...
The steering systems fitted to motor vehicles can broadly be categorised into three types: (1) Mechanical hydraulic power steering systems; (2) Electro-hydraulic power steering systems; (3) Electric power steering systems. I.Electric Power Steering System (EPS) 1. The full English name is Electronic Power Steering, abbreviated as EPS. It utilises power generated by an electric motor to assis...
Design considerations must encompass not only manufacturing processes but also the ease of assembly for OEMs. During the trial production phase of a new automotive model, frequent assembly difficulties arose with the air conditioning refrigeration piping, leading to substantial redesign costs later on. By implementing synchronous engineering for final assembly, virtual assembly analysis and design...
The engine generates power by burning fuel within the cylinders to perform work. As the amount of fuel input is constrained by the volume of air drawn into the cylinders, the engine's power output is consequently limited. Should the engine's operating performance already be at its optimum state, increasing output power can only be achieved by compressing more air into the cylinders to increase the...
1. Power steering feels heavy or lacks assistance Fault Symptom: The steering becomes heavy, with a brief loss of hydraulic assistance. Cause of malfunction: ① Oil pump V-belt slack ② Oil reservoir level too low ③ Insufficient oil pump pressure ④ Pressure control sticking ⑤ Excessive external leakage ⑥ Excessive internal leakage ⑦ Steering shaft bushing too tight ⑧ Front suspension deformation ⑨ A...
