MARKET DYNAMICS

Market dynamics include driving and restraining factors, opportunities and challenges stating the market conditions.

DRIVING FACTOR

"Market growth persists due to logistics demand and durability"

The demand for diesel engines is being pegged largely by the transportation and logistics sector. Diesel engines assure long life and durability with high fuel economy and torque; therefore, they are an accepted choice for long-haul and heavy-load applications. With the ever-increasing volumes of trade and e-commerce, the demand for a reliable freight movement continues for diesel-operated vehicles. This notwithstanding, more electric options are coming through the ranks, although diesel engines seem to flourish in most areas requiring the brute strength and endurance.

"Market growth continues due to industrial demand and reliability"

Diesel engines accomplish huge tasks in industries that require continuous and reliable power, like manufacturing, mining, and construction. Diesel engines are usually employed in standby generators to supply energy to remote areas and during a power cut. The demand for diesel-powered machinery thus grows alongside infrastructure projects and industrialization, especially in emerging economies. While alternative energies are on the rise, diesel engines are still preferred because they excel at efficiency and versatility in hostile conditions.

RESTRAINING FACTOR

"Market growth slows due to regulations and electric competition"

Governments across the world are enforcing stringent emission norms to counter the issue of air pollution, a check for the diesel engines market across industrial segments. Euro 6, EPA Tier 4, and Bharat Stage VI regulations require manufacturers to invest in advanced emissions control technologies, adding to the cost of production. Further, owing to the environmental concerns, the fast shift toward electric and hybrid vehicles has also been eating into diesel engines' demand in various sectors. This dual pressure on companies in the diesel engine market to reduce compliance costs and develop innovative products due to competitive pressures is eroding their once-dominant market position.

OPPORTUNITY
