3. C4  Technology

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

5. Shindaiwa Engines Better for the environmentBetter for the environment –Lowest emission of any handheld engine Better work environmentBetter work environment –Reduction in smelly fumes and a lower exhaust tone Better PerformanceBetter Performance –Patented C4 Technology ® four-stroke design has performance-enhancing Power Boost Chamber –Greater torque then comparable two-stroke –Better specific output then (cc/kW then other four strokes.

6. Shindaiwa Engines True all-position utilityTrue all-position utility –Fuel-born lubrication system –C4 Technology ® engines can be operated in any position Business as usualBusiness as usual –Easy to maintain –Use same fuel mix as a two-stroke –No oil to check or dipstick Professional quality and durabilityProfessional quality and durability –Top Quality components –Close tolerance engineering

7. Shindaiwa Engines Maximum EconomyMaximum Economy –Use up to 25% less fuel –The unit will pay for it self in fuel saving alone Broad applicationBroad application –Trimmers –Brushcutters –Hedge trimmers –Blowers –Water Pumps –Multi Tool –Plus more

8. How Technology ® Works –Gasoline/oil mixture drawn into crankcase like two-stroke –The Fuel charge is compressed by the piston and pumped into Power Boost Chamber –Lubricant mixed with the fuel bathes bearings, valve train and friction surfaces –Precisely-timed valves controlling intake and exhaust. –Combustion is maximized Combines best aspect of two-stroke and four- stroke engine designCombines best aspect of two-stroke and four- stroke engine design

9. Superior Technology Push button for C4 animation

10. Design Criteria Meet/exceed EPA2 and stage 2 of the EU emissions requirements Meet feel/features/performance of existing models Be price-competitive with newer technology designs of competitors Accommodate future changes in displacement

11. Emission Output HC (hydrocarbons) + NOx (oxides of nitrogen) *initial production without a catalyst!

12. Features of a C4 Engines Chromed Cylinder 2-Ring Piston –No oil control ring needed Ball and Needle-Bearing Supported 3-pc. Crankshaft

13. 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

14. 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)

15. 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

16. 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!

17. All-Position Operation Operational necessity for commercial unit Other 4 cycle competitive models not designed for sustained out of position operation

18. 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)

19. Other Features Power Boost Chamber –Pressurized air/fuel/oil mix –Supercharging effect –Sealed crankcase –Patented process –Unique to Shindaiwa

20. No Dipstick

21. C4  Models 12 Models –T/C2510 –T/C3410 –EB2510 –EB3410 –EB8510 –DH2510T –HT2510 –AHS2510 –M2510 –GP3410 (Coming Soon)

22. 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

23. Our Company, Our Products, Our Reputation, are all built upon one principle; Quality in everything we do. Quality in everything we do.
