Cut sectional teaching model of a single-cylinder 4-stroke water-cooled diesel engine — demonstrates the diesel cycle mechanics + fuel injection system + hot-coil starting device visible in metal + plastic construction. Shows all 4 strokes of diesel operation: intake (air only, no fuel), compression (high compression ratio for auto-ignition), power (fuel injected at TDC, ignites from heat of compression), exhaust. Water-cooling jacket visible. Fuel injector + hot-coil pre-heat start visible. Mounted for tabletop demonstration. $349.99 direct.

What students see in the cutaway

  • Cylinder + piston — high-compression-ratio design (16-22:1 typical vs 8-12:1 for petrol)
  • Fuel injector — high-pressure nozzle at cylinder head
  • Injection pump — precision fuel metering + timing
  • Hot-coil starting device (glow plug) — pre-heats combustion chamber for cold start
  • Water cooling jacket — surrounds cylinder, connects to radiator (indicated)
  • Crankshaft + connecting rod — power transmission
  • Camshaft + valves — timing coordination
  • Compression volume — small combustion chamber at TDC

Diesel cycle explanation

Stroke Diesel process vs Petrol (Otto)
1. Intake Air only pulled in (no fuel yet) Air + fuel mixture pulled in
2. Compression Air compressed 16-22× (temperature rises to 500°C+) Mixture compressed 8-12×
3. Power Fuel injected at TDC → auto-ignites from heat Spark plug ignites mixture
4. Exhaust Burnt gases expelled Burnt gases expelled

FAQ

What's the difference between 4-Stroke Diesel + 4-Stroke Petrol models?

Diesel: high compression ratio (16-22:1), fuel injected at TDC, auto-ignites from compression heat, glow plug for cold start, more efficient (30-45% thermal efficiency), higher torque at low RPM. Petrol: lower compression (8-12:1), fuel mixed with air before intake, spark plug ignition, no glow plug needed, less efficient (25-30%), higher power at high RPM. Both models teach 4-stroke cycle but different combustion physics.

Does this actually run?

No — cut sectional teaching model, not a functional engine. Students see internal components + fuel injection + glow plug clearly. For running diesel demos, look at running diesel trainer engines ($3K-$8K).

Is a schematic included?

Instructor's guide + P-V diagram card available on request. Component labels present on the model.
