PERFORMANCE REQUIREMENTS FOR CONSTANT SPEED COMPRESSION IGNITION (DIESEL) ENGINES FOR AGRICULTURAL PURPOSES (upto 19 kW)
summary
Constant speed compression ignition (diesel) engines up to 19 kW for agricultural purposes are small power-generating engines used in irrigation pumps, threshers, generators, and other farm equipment. These engines operate at a fixed speed to ensure consistent performance, fuel efficiency, durability, and reliable power output in rural and field conditions.
Why BIS Certificate is Mandatory for PERFORMANCE REQUIREMENTS FOR CONSTANT SPEED COMPRESSION IGNITION (DIESEL) ENGINES FOR AGRICULTURAL PURPOSES (upto 19 kW)
BIS certification is mandatory to ensure diesel engines meet prescribed standards for safety, performance, fuel efficiency, and emission control. Since these engines are widely used in agriculture, certification prevents substandard products, ensures operational reliability, protects farmers from equipment failure, and supports regulatory compliance under Indian quality control requirements.
What is BIS Certified for PERFORMANCE REQUIREMENTS FOR CONSTANT SPEED COMPRESSION IGNITION (DIESEL) ENGINES FOR AGRICULTURAL PURPOSES (upto 19 kW)
The BIS certified specification defines technical requirements including rated power, fuel consumption, speed regulation, endurance performance, cooling efficiency, noise limits, and construction safety. It also covers testing procedures, marking requirements, and inspection criteria to ensure constant speed diesel engines deliver reliable and standardized performance for agricultural applications.
