S195 Single Cylinder Diesel Engine: Specifications, Applications, and Buyer’s Guide
The S195 is a single-cylinder, four-stroke diesel engine used in selected agricultural, irrigation, and general-purpose machinery. Many versions are water-cooled and use a horizontal cylinder layout, but specifications and mounting details can vary between manufacturers and configurations. A commonly referenced S195 configuration has a 95 mm bore and a 115 mm stroke, which corresponds to a calculated displacement of approximately 815 cm³. Use those figures as an identification reference—not a substitute for the exact manufacturer’s datasheet—when matching an engine to your equipment.
This guide explains what to check before purchasing an S195, including the specifications that affect compatibility, application fit, supplier questions, and sourcing considerations. We recommend confirming the nameplate, rated operating conditions, shaft and mounting dimensions, and cooling arrangement before requesting a quotation. These checks help buyers compare like-for-like engines and reduce the risk of ordering an incompatible unit.
Key Takeaways
- The S195 designation identifies a commonly used single-cylinder diesel engine family, but it does not guarantee that every supplier’s version has identical specifications.
- A frequently cited configuration uses a 95 mm bore, a 115 mm stroke, and approximately 815 cm³ displacement; verify these values against the specific model offered.
- Application fit depends on more than engine power: check speed, output shaft, mounting, cooling, starting method, and the machine’s operating requirements.
- Ask suppliers for a model-specific datasheet, configuration details, inspection information, and clear terms for minimum order quantity and lead time.
Who This Guide Is For
This guide is intended for agricultural machinery manufacturers, equipment importers, distributors, maintenance businesses, and procurement teams evaluating an S195 engine for new equipment or replacement. It is also useful for buyers comparing offers from multiple factories or traders. If you are sourcing engines for resale, request consistent documentation and configuration details so your team can compare products accurately.
What Is an S195 Single Cylinder Diesel Engine?
An S195 is a single-cylinder diesel engine model designation associated with machinery applications that need a compact, independent power source. “Single cylinder” describes the engine’s basic cylinder arrangement; it does not, by itself, define rated output, fuel consumption, emissions compliance, or interchangeability. The same model code may be offered with different accessories, starting systems, shaft arrangements, and production specifications.
Core Design and Operating Context
Many S195 engines are supplied as water-cooled, four-stroke units, but buyers should confirm both features for the actual product being quoted. Cooling-system components, flywheel or pulley options, and the direction and dimensions of the output shaft can affect installation. An engine should therefore be assessed as a complete configuration rather than by model name alone.
Specifications to Confirm Before Ordering
Published S195 specifications can differ by manufacturer and market. The table below gives a useful starting point for identifying an engine, while clearly separating commonly referenced dimensions from details that must be confirmed with the supplier. Request a current datasheet tied to the exact model and configuration in your quotation.
| Specification | Common reference or buyer check | Why it matters |
|---|---|---|
| Engine type | Single-cylinder diesel; confirm cycle and cooling method | Establishes the basic design and system requirements |
| Bore and stroke | A commonly referenced configuration is 95 mm × 115 mm | Helps identify the engine variant; dimensions alone do not prove interchangeability |
| Displacement | Approximately 815 cm³ for the 95 mm × 115 mm configuration | Useful for checking model identity and comparing datasheets |
| Rated output and speed | Obtain the supplier’s rated power, rated speed, and duty conditions | Determines whether the engine suits the driven machine |
| Installation details | Confirm mounting dimensions, shaft size, rotation, and accessory layout | Prevents avoidable fitment and connection problems |
| Starting and cooling | Confirm starting method and included cooling-system parts | Affects operation, installation, and maintenance planning |
Applications and Application Matching
S195 engines may be considered for agricultural and general-purpose equipment where the machine design calls for a single-cylinder diesel power unit. Potential uses can include compatible irrigation or processing equipment, but suitability depends on the required output, operating speed, load profile, and installation interface. Do not assume an engine is appropriate for a particular machine simply because another version with the same model designation is used there.
Match the Engine to the Machine
Start with the driven equipment’s manufacturer requirements, then compare them with the engine datasheet. Check whether the rated speed and power are specified for the intended duty, and confirm how power is transmitted through the shaft, pulley, coupling, or other interface. Also consider the working environment, access for maintenance, cooling arrangements, and the availability of replacement parts in your market.

A Practical Selection Framework
- Define the duty. Record the machine type, expected load, operating schedule, and required speed. Ask the equipment designer or original manufacturer for limits when the engine is a replacement.
- Confirm the configuration. Provide the supplier with photographs, nameplate information, and dimensional drawings where available. Identify the cooling system, starting method, output shaft, mounting points, and any required accessories.
- Compare rated data. Review rated power and speed, fuel and lubrication requirements, and any stated operating limitations on the same basis. If an offer omits a key figure, request written clarification rather than inferring it from the model code.
- Check documentation and inspection. Ask what documents, inspection steps, packaging details, and spare parts are included in the offer. Confirm that the documents correspond to the exact configuration being purchased.
- Evaluate total sourcing fit. Compare the quoted engine and accessories, shipping arrangements, order quantity, lead time, and after-sales communication. A low unit price is not a complete comparison if configuration or delivery terms differ.
Pricing, MOQ, and Lead Time
There is no single dependable price for every S195 engine: quotations can vary with configuration, included accessories, order quantity, packaging, destination, and shipping terms. Minimum order quantities and production or dispatch lead times are also supplier-specific and may change with stock status and order requirements. For a useful comparison, request a written quotation that lists the engine version, included components, quantity, delivery basis, payment terms, and estimated schedule.
For replacement purchases, send the supplier the existing engine’s nameplate details and installation measurements before asking for a price. For volume procurement, provide expected quantities and delivery timing so the supplier can confirm the applicable MOQ and schedule. Treat any quoted lead time as a planning estimate until the order configuration and delivery terms are agreed.
Supplier Evaluation Checklist
- Can the supplier provide a datasheet for the exact S195 configuration being offered?
- Are rated power, speed, cooling, starting method, and installation dimensions clearly stated?
- Does the quotation identify included accessories, packaging, quantity, and delivery terms?
- Can the supplier explain its inspection and documentation process without making unsupported performance claims?
- Are MOQ, estimated lead time, payment terms, and the process for technical questions stated in writing?
Common Buying Mistakes to Avoid
A frequent mistake is treating “S195” as a complete specification. Model names are useful for narrowing the search, but buyers still need to verify the individual engine’s dimensions, rating, and interfaces. Another risk is comparing prices for different configurations, such as an engine supplied with different accessories or packaging.
It is also unwise to assume that an engine will fit based only on bore, stroke, or a photograph. Confirm the output shaft, mounting points, rotation, and connections against your equipment. If the supplier cannot confirm an important requirement from available information, obtain a drawing or technical review before placing a production order.

Conclusion: How to Choose an S195 Engine
The S195 can be a suitable option when its verified specifications match the machinery’s power, speed, cooling, and installation requirements. A commonly referenced version has a 95 mm bore, a 115 mm stroke, and approximately 815 cm³ displacement, but buyers should confirm every value for the engine actually offered. The model designation alone is not enough to establish compatibility.
Before ordering, prepare your application requirements and installation details, request a model-specific datasheet, and compare quotations that describe the same configuration and delivery terms.
