Automotive Engine Metals Market

Automotive Engine Metals Market

Automotive Engine is one of the vehicle's most essential components. It enables the vehicle to function efficiently and run smoothly without any trouble. Vehicle emission, efficiency and overall performance of every vehicle depend on the condition of an automotive engine. Therefore, it is important for engine manufacturers to use a material that is suitable for high speed and high-temperature applications. Also, there are various rotating and reciprocating parts in the engine, which makes it important for the material to be wear-resistant to improve the efficiency of the engine.

In this report, we look at the metal materials which are used in the major parts of an automotive engine like the crankshaft, cylinder head, piston, etc.

The crankshaft is a part of the engine which translates reciprocating linear piston motion into rotation. It transforms reciprocal movement into rotation through crankpins, extra bearing surfaces whose axis is offset from that of the crank to which each cylinder attaches the large ends of the connecting rods. The crankshaft is connected to a flywheel to reduce the pulsation characteristics of the four-stroke cycle and also act as a torsional or vibrational damper at the opposite end. The crankshaft is usually made from steel. Usually, iron and a small percentage of carbon, approximately 0.25% to 0.45% are used in medium-carbon steel alloys along with combinations of alloying elements like chromium, molybdenum, aluminum, etc.

The head of the cylinder is a casting bound to the top of the cylinder block. It houses the spark-plug or injector location holes, inlet, and exhaust poppet-valves forms the upper face of the combustion chamber and takes the combustion pressure reaction. The coolant passages, cavities, intake and exhaust ports, lubricating passages, and the spark plug or injector bosses are also located within or injector bosses are also located within the head casting. The cylinder head is detachable to allow simple access to the valves and piston tops and to facilitate the cylinder bore, combustion chamber, and valve ports machining. The materials generally used are gray cast iron and aluminum alloys. The popular cylinder head cast iron meets most of the specifications, such as good castability, good machinability, good resistance to corrosion, adequate rigidity, strength and hardness, cheapness and low thermal expansion. But it has the disadvantages of high weight and low thermal conductivity. On the other hand, the aluminum alloy head has half the weight of the corresponding cast-iron heads. It also has a thermal conductivity three times better than that of cast iron due to which the possibility of thermal distortion is reduced and the head cooling system permits the use of higher compression ratios. The disadvantages of aluminum alloy are that it is more expensive, its corrosion resistance is inferior to cast iron, it is much softer than cast iron, and it has a high thermal expansion which causes fretting between an aluminum alloy head and a cast-iron cylinder block during starting and stopping of engines so that separate wear-resisting valve seats and guide inserts become necessary.

A flywheel is a mechanical device intended to store rotational energy effectively. Flywheels resist changes in rotational speed. Depending on the application, flywheels are made of different materials. Old steam engines use cast iron flywheels. Flywheels used in car engines are made of cast or nodular iron, steel or aluminum. Flywheels made from high-strength steel or composites have been proposed for use in vehicle energy storage and braking systems.

Cylindrical blocks are cast parts that make up the engine body. Cylinders are machined as a part of the block. Other important parts, such as the valves, inlet, and exhaust manifolds, crankshaft, etc. all attach themselves to the cylinder block. The cylinder block is generally the heaviest part of the engine. The cylinder blocks are cast from gray iron or an iron alloy containing nickel or chromium for high strength and wear resistance. Some cylinder blocks are cast from a silicon-aluminum alloy.

The automotive piston is an engine component cylindrical in shape, which slides back and forth in the cylinder bore due to the force produced by the expansion of gas during the combustion process. Piston system comprises a piston, piston rings, and piston pin; this system transfers the generated force to the crankshaft through the connecting rod. Piston generates mechanical energy that propels the crankshaft movement, which in turn, drives the wheels of the vehicle. Gasoline engine piston usually has fewer piston rings than diesel engine pistons due to a high compression ratio of the latter. Most of the pistons are made up of aluminum & steel alloys to withstand high temperatures.

Engine valves are located in the cylinder head. Engine valves have the primary purpose of letting air in and out of the cylinders. That air is used to assist the ignition of the fuel that drives the piston up and down. The most common materials used for engine valve applications include carbon steel alloys, stainless steels, high-strength nickel-chromium-iron alloys, and titanium.

Connecting rods form the link between the crankshaft and the pistons and transfer the gas and inertial forces to the crankpins on the crankshaft. The piston is pushed in and out of the cylinder by the connecting rod. The most common material used for making rods is steel, but T6-2024 and T651-7075 aluminum alloys can also be used (for the ability to absorb high impact at the expense of durability and lightness) or titanium (for a combination of lightness with strength, at higher cost) for high-performance engines, or of cast iron for applications such as motor scooters.

In automotive, the supply of fuel/air mixture to the cylinders is carried out by the intake manifold whereas the exhaust manifold collects the exhaust gases from multiple cylinders into one pipe. The intake manifolds are manufactured from aluminum or cast iron, whereas exhaust manifolds are made from cast iron or stainless steel.

Spark plugs are used to provide a place for an electric spark that is hot enough to ignite the air/fuel mixture inside the combustion chamber of an internal combustion engine. This is achieved by the arcing of a high voltage current across a gap on the spark plug. A spark plug is made of a center electrode, an insulator, a metal casing or shell, and a side electrode. High-Nickel alloys are typically used for the electrodes, whereas aluminum oxide is used for the insulator and the shell is made out of steel. Furthermore, exotic and precious metals are increasingly being used by manufacturers. Several newer plugs use silver, gold, and platinum in the electrodes. Silver has higher thermal conductivity than other electrode metals, while platinum has great resistance to corrosion.

Among the various materials used to make the different parts of an engine, the most common metals used are steel, iron, and aluminum. These materials are usually alloyed to give specific properties required by the part. The most common alloying materials are Nickel, Chromium, and Silicon.

Based on the vehicle type, the passenger vehicle segment is expected to hold the most prominent share in the automotive engine metals market. This is due to the growing automotive sector worldwide supported by the growing disposable income in several regions. According to the International Organization of Motor Vehicle Manufacturers, the number of passenger cars sold increased from 49,650,336 in 2009 to 70,849,466 in 2017 and is expected to further grow and acts as one of the main factors for the growth of the automotive engine metals market.
