Automotive fuel injectors are components that are responsible for the final stage of fuel delivery in fuel injection systems. High pressure fuel is delivered to the injector, which is activated by an engine control unit or fuel injector control module. When activated, the injector momentarily opens a valve that allows a precise amount of fuel to enter into the combustion chamber. The fuel injector consists of a valve which is opened by means of either an electric solenoid valve or fuel pressure. The amount of fuel to be injected depends on the timing of valve opening. The injectors are alternative for the carburetor, in which fuel is drawn due to the downward stroke of the piston. In case of an injector, the fuel is pumped at high pressure, by means of a fuel pump.
Fuel injectors are a more precise means of performing mixing, atomization, and injection of fuel in the cylinder. The need of varying air-fuel mixture requirements, according to the situation of loading and speed, is fulfilled by the injectors, while the carburetors are unable to perform the same. The injectors supply a precise amount of fuel as per the requirement, which increases efficiency of the engine. This is a key driver of the automotive fuel injector market.
The main restraint to the fuel injector market is the short lifespan of injectors, as compared to carburetors, coupled with the higher cost. The injectors are critical to repair. The amount of unburnt hydrocarbons increases due to the direct injection of fuel, which leads to a rise in pollution.
The demand for vehicles is increasing day by day. Asia Pacific countries such as India and China are giant market for the automotive industries. The demand for injectors is likely to increase due to the rise in demand for vehicles. This is anticipated to present significant growth opportunities for the automotive fuel injector market. However the increasing demand for electric vehicles may affect this growth, as the injector is not needed in it. But, for the forecast period of 2017-2025, the automotive fuel injector market is anticipated have growth.
The automotive fuel Injector market can be segmented based on vehicle, fuel injected, pressure range, activating source, type of nozzle, mounting, sales channel, and geography. In terms of vehicle, the automotive fuel injector market can be segregated into passenger vehicles and commercial vehicles. The commercial vehicles segment can further classified into light commercial vehicles, heavy commercial vehicles, and buses & coaches. Depending on the vehicle, the number of cylinder vary and subsequently, the number of injectors also vary. In terms of fuel injected, the automotive fuel injector market can be segmented into gasoline fuel injectors and diesel fuel injectors. Both type of fuels require different air-fuel ratio. Therefore, different types of injectors are utilized in order to maintain the different air-fuel ratio.
Based on pressure range, the automotive fuel injector market can be segregated into low pressure injectors and high pressure injectors. Low pressure injectors are capable of handling fuel pressure up to 20 Mpa, while the high pressure injectors are capable of handling fuel pressure between 20 Mpa to 40 Mpa.
In terms of activating source, the automotive fuel injector market can be classified into electronic unit injector and hydraulic unit injector. In case of an electronic unit injector, the opening and closing of the valve is controlled by a solenoid actuator. While in case of a hydraulic unit actuator, hydraulic pressure is utilized for opening and closing of the valve. The hydraulic pressure is generated by pumping engine lubricant to a controllable high pressure.
In terms of type of nozzle, the automotive fuel injector market can be segregated into single-hole nozzle, multi-hole nozzle, pintle nozzle, and Pintaux nozzle. In a single-hole nozzle injector, only one hole injects the fuel, while in a multi-hole nozzle injector, more than one hole injects the fuel. The number of holes in a multihole nozzle injector can vary from 4 to 18. In a pintle nozzle injector, the stem of the nozzle is extended to form a pin, or pintle, which protrudes through the mouth of the nozzle body. In this injector, the spray angle is generally 600. The Pintaux nozzle injector is a type of pintle nozzle in which an auxiliary hole is provided. Small amounts of fuel is injected from this auxiliary hole before main injection.
In terms of mounting of the injector, the automotive fuel injector market can be segmented into throttle body injector, central port injector, and multiport and direct fuel injector. In a throttle body injector mounting, the fuel is directly injected into the throttle, just before the cylinder intake valve. In this case, the number of injectors is equal to the number of cylinders. In a central port injector, the fuel is injected by means of a single maxi injector. In this case, there is only one injector for any number of cylinders. In case of multiport and direct injectors, the fuel is directly injected inside the cylinder. Most gasoline and diesel engines utilize this type of injector.
Based on sales channel, the automotive fuel injector market can be segmented as Original Equipment Manufacturer (OEM) and aftermarket. OEM market segment is dominating the fuel injector market because of the contracts between the manufacturers and the OEM. Aftermarket segment generates more revenue per unit of fuel injectors.
Based on geography, the automotive fuel Injector market can be segmented into North America, Asia Pacific, Europe, Middle East & South Africa, and Rest of World. Asia Pacific is a large market for automotive, where the demand for automobiles is boosting the demand for automotive components. North America witnessed a higher demand for commercial vehicles than other regions. Hence, the demand for automotive fuel injectors in the commercial vehicle segment is anticipated to be higher in the region.
Increasing demand for automobiles propels the demand for injectors. Therefore, manufacturers are concentrated on fulfilling the increased demand for the injectors. Key players operating in the automotive fuel injector market include Robert Bosch GmbH, Continental AG, Delphi Automotive LLP., Hitachi Ltd., DENSO CORPORATION, Infineon Technologies AG, Keihin Corporation, Woodward, Inc, and Magneti Marelli S.p.A.
