What is C4 Technology?
• Charged • Compression • Clean • Combustion
• Shindaiwa’s answer to emission requirements for the
foreseeable future!

Features of a C4 Engines
• Chromed Cylinder• 2-Ring Piston
– No oil control ring needed• Ball and Needle-Bearing
Supported 3-pc. Crankshaft
Features of a C4 Engines
• Overhead Valve/Pushrod Design
• Adjustable forged rocker arms
• Cam– Hi-lubricity polymer nylon
(HLP)– Best compromise between
noise & wear• Decompression System
– Cam lobe type
Features of a C4 Engines
• PCI Programmed Controlled Ignition– Internally advancing module– Easier starting– RPM limiter (10,500)– Smooth, stable idle– Idle warm up for cold starts
(+200 RPM)– Replaceable coil wire (6 x
75mm)
Features of a C4 Engine
• Walbro WYL Carburetor with Primer
• Fuel tank– Largest capacity micro 4-
stroke– T/C2510 runs up to 33%
longer than a T/C230– 1 hour run time (approx)– Operator/application-
dependent
Features of a C4 Engines
• High RPM• Competitive power with 2-stroke• Comparable throttle response with
2-stroke• True all-position operation• Similar service/maintenance
requirements with 2-stroke• Low fuel consumption• Low emissions• Quiet!
All-Position Operation
• Operational necessity for commercial unit
• Other 4 cycle competitive models not designed for sustained out of position operation
Throttle Response
• Key design requirement• Poor on prior micro 4-stroke
designs• Excellent on all the • Same as other 2-stroke
Shindaiwa engines – (The engine response on Shindaiwa
models is among the best in the industry)
Other Features
• Power Boost Chamber – Pressurized air/fuel/oil
mix– Supercharging effect– Sealed crankcase– Patented process– Unique to Shindaiwa
No Dipstick
C4 Models
• 12 Models– T/C2510
– T/C3410
– EB2510
– EB3410
– EB8510
– DH2510T
– HT2510
– AHS2510
– M2510– GP3410 (Coming Soon)
Summery • Environmentally friendly• Low fuel consumption• Operates and feels like a 2-
cycle unit• 12 models to chose from• More are coming • This is the engine for the
future
