Description

Knock Sensor Market Size:

Knock Sensor Market is forecasted to rise at a 4.74% CAGR, reaching USD 1,016.364 million by 2030 from USD 806.330 million in 2025.

A knock sensor is a device used in internal combustion engines to detect and respond to engine knock or vibration, which can cause damage to the engine, and the knock sensor sends signals to the engine control unit (ECU), which then adjusts the ignition timing and fuel injection to prevent knocking. A knock sensor comes in different types, such as piezoelectric resonant and piezoelectric non-resonant sensors, and can be used in automotive, construction, and industrial applications. The market for knock sensors is mainly driven by the increasing demand for fuel-efficient vehicles, stricter emission regulations, the increasing production and sales of automobiles worldwide, and demand for heavy equipment and machinery in construction and industrial applications.

Knock Sensor Market Growth Drivers:

  • The increasing automotive production and growing construction activities are augmenting the knock sensor demand during the forecast period. 

Knocking can cause damage to the automobile engine components, such as the pistons and connecting rods, leading to costly repairs or even engine failure. A knock sensor is a vital component of modern engine management systems in automobiles as it is used to detect and prevent the knocking in the engine, and these can improve engine performance, efficiency, the engine's lifespan, and fuel economy and reduce emissions. The increasing production and usage of automobiles and stricter emission regulations will increase the demand for the knock sensor. 

Knock sensors, such as generators, compressors, and heavy machinery, are also used in construction and industrial applications to improve engine performance, efficiency, and reliability. In industrial and construction applications, engines are often subject to heavy loads and harsh operating conditions, which can increase knocking and other forms of abnormal combustion. The knock sensors help to ensure that the engine operates within safe limits and maintains optimal performance under challenging conditions, thereby reducing its maintenance costs and prolonging its performance life. Overall, the demand for knock sensors increases with growth in industrial and construction activities. According to the Association of Equipment Manufacturers (AEM's) "2021 Equipment Market Outlook" report, North America's industrial equipment and heavy machinery sales increased by 6% from 2020 to 2021.

Knock Sensor Market Geographical Outlook:

  • The Asia Pacific region is expected to hold a significant market share.

Asia-Pacific region is expected to hold a significant market share due to the growing automotive industry in countries such as China, South Korea, and India, increasing government regulations regarding emissions and fuel efficiency, and increasing construction activities. In May 2021, the Chinese government released an "Automotive Industry Development Plan (2021-2025)" to support the development of advanced manufacturing technologies in the automotive industry in China over the next five years, which require knock sensors for engine management and efficiency. In 2020, the Indian government launched the Production Linked Incentive (PLI) Scheme with an allocation of INR 51,311 crores for ten manufacturing sectors, including automobiles, electronic products, pharmaceuticals, textiles, and others. The government of South Korea launched the "Korean New Deal" program in 2020 with plans to invest KRW 1.7 trillion (approximately USD 1.4 billion) over the next five years in the development of advanced powertrain technologies, including knock sensors and other components that are critical for improving the efficiency and performance of the engine.
