Basics
- A (Series of?) Single Cylinder Spark Ignition Engine(s) by Honda
- Stock are Gasoline, need to see if stock Propane / Autogas etc exist
- Commonly used for Gas Powered Pumps , Gas Powered Pressure Washers etc
Stock Specifications
- Carbureted
- OHV Based
- Automatic decompression system (releases valves for the hand pull cord “spin up” to make it easier (if i understand correctly), not as essential as in small diesel engines but neat regardless
- Quote from the EU Site:
- 4 stroke single cylinder
- OHV petrol engine
- 25° inclined cylinder horizontal shaft
- CYLINDER SLEEVE TYPE:
- Cast iron sleeve
- BORE X STROKE:
- 68 x 54 mm
- DISPLACEMENT:
- 196 cm³
- COMPRESSION RATIO:
- 8.5 : 1
- NET POWER
- 4.3 kW ( 5.8 HP ) / 3600 rpm
- CONT. RATED POWER
- 3.3 kW ( 4.4 HP ) / 3000 rpm
- 3.7 kW ( 5.0 HP ) / 3600 rpm
- MAX. NET TORQUE
- 12.4 Nm ( 1.26 kgfm ) / 2500 rpm
- IGNITION SYSTEM
- Transistorised
- STARTER
- Recoil (el. start optional)
- FUEL TANK CAPACITY
- 3.1 Liter
- FUEL CONS. AT CONT. RATED POWER
- 1.7 L/h - 3600 rpm
- ENGINE OIL CAPACITY
- 0.6 Liter
- DIMENSIONS (L X W X H)
- 321 x 376 x 346 mm
- DRY WEIGHT
- 16.1 kg
Potential Modifications
New Frame / Fuel Tank etc
- Mainly making it into a Powercube
- Could also in theory make it into a generator cart type thing, or a generator in a hush box
New Air Intake
- Uncertain how much it would help, but could use a Cold Air Intake type thing
Fuel Injection
- Would need an Open Source ECU , a new Wire Harness , a Fuel Pump/Rail, and the nozzles (probably plus either drilled+tapped holes, or a custom milled/cast cylinder head
- Port Injection, Direct Injection , or Dual Injection
Fuel System
- Upgrade the Fuel System (If Needed: Tank, Pump, Fuel Lines/Fuel Rail, Fuel Injectors, etc) to handle E-58 or ideally pure Methanol / Ethanol etc (Also look into Racing Gasoline
- Add in an Autogas System (Most likely Gas Phase, although especially with high rpm and/or boost, Liquid Phase Autogas Systems are interesting due to the cooling effect
- Water Injection / Methanol Injection are semi related
New Piston
- Could have it DLC Coated (also potentially WPC treatment etc)
- Could REALLY benefit if you also used a 3D Printed Internal Combustion Engine Piston
New Sleeve
- Different Metals
- Needs to be looked into more before i add to this section (unless any of you know more of course!
New Valves
- Sodium Filled Internal Combustion Engine Valves
- and/or larger valves / dual valves (2 intake, 2 exhaust), and/or more widely available valve form factor
New Ignition System
- Higher than stock revs, and ‘’supposedly’’ a pile of boos+fuel will make stock ignition unreliable
- This seems like an unlikely need, but still worth looking into
- Also need to see how easily the stock “transistorized ignition system” meshes with the os ecu and such
Oil System Upgrades
- A better oil filter / a Bypass Oil Filter
- A better Oil Pump
- Via a larger pump, or one operating on a separate circuit from lubrication, yet tied to the same Wet Sump it could be made into an Oil Cooled Engine (performance closer to a Water Cooled Engine but with less complexity (although unlike a PROPER oil cooled engine, it probably wouldn’t have the oil channels near TDC etc to really optimize the effect), could maybe do this with custom parts perhaps?
- Upgrade to a Dry Sump system
Camshaft Upgrades
- Need to see what it actually HAS first, but especially with alternative fuels and/or mods messing with the compression ratio, having something like IVVT would be helpful, could also allow for the Atkins Cycle etc
- More simple mechanically, albeit more complex fabrication capability wise would be something like DOHC etc for efficiency optimized for multiple rev bands, but this isn’t as needed for a stationary engine that should optimally be held at a certain rom unlike a constantly accelerating/decelerating motor vehicle.
Forced Induction
- Turbochargers and Superchargers
- Lots of Cost+Complexity so not something I’m looking into for a small single engine system
- ALTHOUGH some sort of Exhaust Heat Recovery system would be neat
