About Automotive Knock Sensor
A knock sensor is a piezoresistive sensor where the signal is varied based on the amount of force or pressure applied to it. The knob-like part that is linked to the car's engine helps in sensing engine knock. Knocking or simply called as knock occurs in spark ignition internal combustion (IC) engines when the combustion of the air-fuel mixture in the cylinder does not start off correctly in response to ignition by the spark plug. Knocking occurs in diesel engines also but in a different way. In diesel engines, during cold starting conditions, there would be improper vaporization in the cylinder, which results in accumulation of fuel droplets.
Technavio’s analysts forecast the global automotive knock sensor market to grow at a CAGR of 3.76% during the period 2017-2021.
Covered in this report
The report covers the present scenario and the growth prospects of the global automotive knock sensor market for 2017-2021. The report presents a detailed picture of the market by way of study, synthesis, and summation of data from multiple sources.
The market is divided into the following segments based on geography:
Technavio Announces the Publication of its Research Report – Global Automotive Knock Sensor Market 2017-2021
Technavio recognizes the following companies as the key players in the global automotive knock sensor market: Bosch, Continental, Delphi*, DENSO, and NGK Spark Plugs.
Other Prominent Vendors in the market are: Hitachi, Hyundai KEFICO, INZI CONTROLS, Standard Motor Products, and Wells Vehicle Electronics.
Commenting on the report, an analyst from Technavio’s team said: “One trend in the market is flat response knock sensor. The design of flat response knock sensor allows its usage in various types of IC engines like two-stroke engines, alternative fuel engines, diesel engines, and flexible fuel engines. This sensor is a self-generating piezoelectric sensor, which is mounted either on the engine block or on the cylinder head.”
According to the report, one driver in the market is growing adoption of sensors in powertrain systems. The rising demand of consumers and increased OEM offerings have led to the widening of several parameters in the vehicles like safety, performance, stability, and comfort. The evolution of electronic components from the conventional mechanical components has refined and improved these parameters. The growth of electronics in vehicles eventually surpassed the growth of the entire automotive industry. Introducing special features in vehicles through the addition of electronic components is the only way to showcase product differentiation for sustaining the competition. It is believed that 90% of the enhanced features in any car model is possible by the addition of electronic components.
Further, the report states that one challenge in the market is cost pressures on sensor manufacturers. Automotive manufacturers undergo certain pressures as they are subjected to the dynamism of technology and the regulations by the governments. Increasing environmental and safety standards are leading to the additional cost for the manufacturers to comply with these standards regarding technologies in vehicles. Emission standards like the US CAFE standards that became effective in 2016 have increased the manufacturing cost of a vehicle by $1,000. Automotive OEMs need to invest additional costs in maintaining expenses of R&D and production because of the dynamic changes in emission standards.
