Rating and speed: the original general description also mentions 1800 and 2000 rpm. Those speeds need a separate confirmed power rating and governor specification. The 1500 rpm data above should not be applied to another speed, or treated as a continuous-duty rating without the applicable data sheet.

Clutch, belt-pulley and PTO configuration

Specify how the engine will connect to your driven equipment. Include the required output speed, shaft dimensions, rotation direction and coupling or pulley arrangement. Request an installation drawing to check mounting and alignment before purchase.

  • Drive connection: discuss the clutch assembly, belt pulley or PTO shaft required for the project.
  • Fuel and controls: the existing listing offers a fuel tank and automatic controller as options; confirm inclusion and functions in the quotation.
  • Cooling package: the listing describes a radiator with a belt-driven fan and safety guard, with a stated 40°C maximum. Ask for the ambient-temperature and ventilation requirements of the quoted package.
  • Electrical and filtration: the listing includes a 12 V charging alternator, dry-type air filter, fuel filter and oil filter. Confirm the complete starting and charging package.

Product photos: the current gallery images are labelled K4100P. Request current ZH4100P photos and a nameplate image to confirm the appearance and supplied configuration.

Information needed for engine selection

For a pump, belt-driven machine or another mechanical drive project, send the equipment data so the engine and output assembly can be checked together.

  1. Equipment type and required shaft power, including starting or peak load.
  2. Required engine and driven-equipment speeds, operating hours and load pattern.
  3. PTO, clutch, pulley or coupling dimensions, mounting drawing and rotation direction.
  4. Site temperature, altitude, ventilation and installation space.
  5. Destination, quantity, required accessories and any applicable emissions or certification requirements.

ZH4100P diesel engine FAQ

What is the listed power output of the ZH4100P?

The detailed listing specifies 30.1 kW at 1500 rpm as a 12-hour power rating. Obtain the current data sheet to confirm the rating definition, operating conditions and permitted duty for your application.

Can I order a clutch, belt pulley or PTO shaft?

These are configuration enquiries to discuss with Alexerpower. Send the connection dimensions and driven-equipment requirements, and confirm the exact assembly and included accessories in the quotation.

Are ZH4100P and K4100P interchangeable?

Do not assume interchangeability from the model names or shared gallery photos. Compare the engine nameplate, power and speed rating, mounting dimensions, rotation direction and output connection for the two actual assemblies.

What does the fuel consumption figure mean?

The published value is ≤248.8 g/kW·h, expressed as specific fuel consumption. It is not a fixed litres-per-hour figure for every load. Request the test conditions and fuel-consumption data at your intended operating point.

Does this page confirm an emissions certificate or warranty?

It does not specify an emissions certification, warranty period or delivery lead time. Request the documents and commercial terms applicable to the exact model and destination before placing an order.
