Foton 1.2L Inline-4 Gasoline Engine 4W12M1
Basic Specifications & Core Structural Parameters
| Category | Technical Item | Official Standard Data | Remarks / Notes |
|---|---|---|---|
| Basic Info | Cylinder Arrangement | Inline 4-Cylinder (L4 / I4) | Classic 4-cylinder layout for mini-trucks and micro-vans. |
| Working Cycle | 4-Stroke, Water-Cooled | Relies on the front radiator and coolant circulation. | |
| Geometry | Displacement | 1.206 Liters (1206 cc) | Precise actual displacement in cubic centimeters. |
| Valves per Cylinder | 4 (16 Valves Total) | Smoother intake and exhaust at high RPM than older 2-valve models. | |
| Valvetrain | Camshaft Type | DOHC (Double Overhead Cam) | Independent control for intake and exhaust camshafts. |
| Valvetrain Drive Medium | Timing Chain Drive | Maintenance-free design; no need for regular replacement like a timing belt. | |
| Materials | Cylinder Head Material | Aluminum Alloy | Optimizes weight reduction and heat dissipation. |
| Cylinder Block Material | Cast Iron | High strength and wear resistance; resists deformation under heavy loads. |
Power Output & Performance Efficiency
| Category | Technical Item | Official Standard Data | Remarks / Notes |
|---|---|---|---|
| Power Output | Rated Max Power | 63 kW | Equivalent to approximately 86 metric horsepower (ps). |
| Speed at Max Power | 6000 RPM | High-RPM engine; delivers more punch under load at wider throttle openings. | |
| Torque Output | Max Torque | 112 N·m | Ensures sufficient tractive effort when starting from a standstill in low gears. |
| Speed at Max Torque | 4000 - 4400 RPM | The most effective RPM range for hauling and climbing slopes. | |
| Speed Limit | Rev Limiter / Cut-off | Approx. 6500 RPM | Controlled by the vehicle Electronic Control Unit (ECU) for safety. |
Fuel Control & Electrical Systems
| Category | Technical Item | Official Standard Data | Remarks / Notes |
|---|---|---|---|
| Fuel System | Aspiration Type | Naturally Aspirated | Simple mechanical structure; no risk of turbocharger failure or high replacement costs. |
| Fuel Injection Method | MPI (Multi-Point Injection) | Sequential injection into intake ports for uniform combustion; highly mature tech. | |
| Electricals | Ignition System | COP (Coil-on-Plug) | Independent ignition coil per cylinder; maximizes energy for cold/wet starts. |
| Alternator Specs | 14V / 65A - 70A | Sufficient to power aftermarket dashcams, backup cameras, and radar sensors. | |
| Emissions | Emission Compliance | National V (Euro V) / National IV (Euro IV) | Varies based on the specific production year and vehicle registration logbook. |
Maintenance & Consumable Specifications
| Category | Technical Item | Common Recommendations | Remarks / Notes |
|---|---|---|---|
| Engine Oil | Lubricant Capacity | Approx. 3.2 - 3.5 Liters (L) | Buying a standard 4-liter oil jug is sufficient when changing the oil filter. |
| Recommended Viscosity | 5W-30 or 10W-40 | 5W-30 is ideal for winters/northern regions; 10W-40 for summers/heavy loads. | |
| Drivetrain | Matching Gearbox Model | Commonly paired with Qingshan MR513 | 5-speed manual; gear ratios are optimized for low-speed high torque. |
| Clutch Type | Single Dry Plate with Diaphragm | Avoid keeping the clutch half-engaged for long periods to prevent burning the friction disc. | |
| Ignition | Spark Plug Type | Nickel Alloy or Iridium | Recommended to inspect or replace every 30,000 to 40,000 km. |
