China china r175 diesel engine price

The R175 is a single-cylinder, horizontal, four-stroke, water-cooled diesel engine. You must verify the rated output (typically 4.41kW / 6HP) and the rated speed (2600 rpm). Ensure the bore x stroke is 75x80mm. High-quality units should feature forged steel crankshafts and high-strength alloy cylinder liners to ensure a service life exceeding 5,000 hours under standard maintenance.

This engine is a 'workhorse' for small-scale operations. It is primarily used for walking tractors (power tillers), small irrigation pumps, electric generators (3-5kW), and food processing machinery like rice millers. Its compact design and high torque at low speeds make it ideal for rural agricultural environments where fuel efficiency and easy manual starting are prioritized.

Buyers should prioritize suppliers with ISO 9001:2015 certification for manufacturing consistency. For specific markets, check for CE marking (Europe) or EPA/CARB compliance (USA), though the R175 is most commonly exported to Southeast Asia and Africa under national agricultural machinery standards. Always request a factory test report showing fuel consumption rates (typically ≤280.2 g/kWh).

The R175 usually employs a hopper-type (evaporative) water cooling system or a radiator system. For continuous heavy-duty use, the radiator version is preferred to prevent overheating. Regarding lubrication, ensure the engine uses a pressure and splash combined system with a reliable oil pump to protect internal components during high-load operations.

The primary risks include refurbished components being sold as new and under-powered engines (labeling a 5HP engine as 6HP). To mitigate this, use Made-in-China.com's 'Audited Supplier' reports to verify the factory's actual production capacity. Always request a pre-shipment inspection (PSI) to verify the serial numbers and perform a cold-start test.

The R175 is a high-volume commodity. A standard MOQ is often 5-10 units, but significant discounts of 10-15% occur when ordering a full 20ft container (approx. 180-200 units). Negotiate for spare parts kits (pistons, rings, gaskets) to be included at 2-3% of the total order value to handle initial maintenance needs in your local market.

Engines must be shipped without fuel or oil to comply with international maritime hazardous goods regulations. They should be packed in fumigated wooden crates or reinforced double-wall corrugated cartons with iron frames to prevent impact damage. Ensure the supplier applies an anti-rust coating to exposed metal parts to prevent corrosion during sea transit.

Utilize Secured Trading Services provided by Made-in-China.com to ensure payment is only released after the supplier provides the Bill of Lading (B/L). Avoid direct wire transfers to private accounts; always use corporate accounts verified by the platform to prevent fraud.
