FAQs

What engine type and basic configurations are listed for DP158/DP180/DP222 variants?

The manual lists a water-cooled, 4-cycle, V-type diesel engine with turbocharger and air-to-air intercooling, including wet-type cylinder liners and specified bore/stroke and displacement per model.

What cooling system capacities and key temperature limits are provided?

It provides coolant capacities for engine-only and with radiator, coolant flow rates, pressure cap limits, and water temperature ranges for standby/prime and before starting full load.

Which lubrication and fuel-system specifications are included?

The section includes lubrication method, oil pump type and driving method, oil capacity range, oil pressure minima by speed condition, maximum oil temperature, oil class/API and SAE grade. It also specifies injection pump type, governor type, fuel feed pump capacity, injection nozzle opening pressure, and fuel filter details.
