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
