On March 1, 1998, Tanaka became the first two-stroke manufacturer to certify to the stringent C.A.R.B. Tier II emissions regulations. While most other manufacturers tried to fight the Â standard and say that it could not be done with two-stroke, Tanaka said, "WE DID IT!"
Today, all Tanaka products comply with EPA phase 2 regulations and all Tanaka product groups are C.A.R.B Tier II compliant.

Tanaka's innovative two-stroke engine, produces ultra-low emissions without the need for special or additional internal moving parts.
Many people ask us, "When is Tanaka going to build a 4-cycle?" The answer is "We are not!" You don't have to switch to 4-cycle!
Two-stroke is not going away. As other manufacturers push lackluster performing 4-cycle products, Tanaka is committed to providing you with two-stroke powered products now and for the future.
Less moving parts, better power-to-weight, and outstanding throttle response are just a few of the advantages Tanaka products have over 4-cycle or hybrid 4-cycle powered products. Here are some more:
1. Service Costs
Due to the design elements and the additional internal components, labor costs for service and repairs of 4-cycle engines are considerably higher.
Standard compact 4-cycle engines utilize oil reservoirs, however their extremely small capacity requires that the owner check it constantly and change it regularly. Since these engines do consume oil, the likelihood of lubrication related failure is significantly higher.
Two-stroke engines are usually smaller in size and up to 30 percent lighter than compact 4-cycle engines with the same power rating.
Tanaka two-stroke engines provide more usable power and torque at RPMs most suitable for effectively powering handheld products.
5. Internal Components
Compact 4-cycle engines utilize four times the amount of components as Tanaka two-stroke engines. Many of which are moving and subject to excessive wear.
During the intake / compression stroke, the optimized scavenging system within the cylinder and crankcase walls, significantly increase the atomization of the fuel / air mixture which results in a much more efficient combustion process.
Then, in the combustion / exhaust stroke, the exhaust exits through a small catalytic converter in the muffler where the remaining hydrocarbons turn into carbon dioxide.
Tanaka Muffler # 6692463 TC-4700 & PF-4000. Designed for TC-4700 but will also fit and reduce the noise about 15 to 20% on the PF-4000.
