    Can someone explain to me what the Strato-Charged™ engines are by redmax. Are they the same as the C4 engine by shindaiwa?

    Has anyone had good luck with those types of engines?

    Red Max introduced the "strato charged" engine 5 years ago. The Strato engine is over 30 % more fuel efficient than a regular 2 stroke engine. It does this by intoducing clean air into the cylinder and burning off the gas that used to be discharged into the atmosphere. Red Max spent alot of time and money developing this technology and is leading the industry in meeting the new standards set by the E.PA. and CARB II standards. Most of the competition is either using a catalytic converter or a mix of 4stroke and 2 stroke technology. These Strato engines have proved to be very reliable and light weight. Think of 30% savings on fuel, not only the cost of the fuel but the time saved not having to gas up. These engines are piston ported and have all the commercial qualities that Red Max is well known for. Try one and see for yourself.

    Hi G-Father,

    Here is a quote from this site.

    "Redmax®Strato-Charged™ Engine Development History

    On July 5, 1995, the U.S. Environmental Protection Agency (EPA), approved California's Air Recourses Board's (ARB) authorization request, which made the small off-road engine (including handheld equipment such as string trimmers & chain saws) regulations, the first enforceable California off-road emission control regulations. Many manufacturers believed these strict standards would in effect outlaw two-cycled powered products. These manufacturers argued that the proposed standards were economically unattainable, and the cost to comply would be unacceptable to consumers.

    Komatsu Zenoah, the parent company of RedMax®, with a corporate mission statement that says, "Ensuring a Green Earth with state-of-the-art Technology, we a Steadily Making Efforts to Create a CLEAN & GREEN 21 Century", challenged their engine design engineers to not only meet the proposed CARB Tier II standards but to exceed them.

    In May 1998, two new technology engines from RedMax®/Komatsu Zenoah were the first engines that were Carb Tier II certified without using a catalytic muffler.

    In July 1999, Komatsu Zenoah America introduced seven new RedMax® products powered by the CARB Tier II certified, revolutionary, 25 4cc, Strato-Charged™ low-emission two-cycled engines.

    This new technology, state-of-the-art RedMax®/Komatsu Zenoah Strato-Charged™ low-emission: engine:
    meets clean air standards by introducing fresh air into the engine between the exhaust gases and the fresh charge of air/fuel mix
    reduces emission by more than 70%
    reduces noise levels by 5 decibels
    increases fuel efficiency by 34.5%
    The 34.5% increased fuel efficiency means the commercial land care operator can save over $156.00 in fuel costs, per year, by using any of these new RedMax® Strato-Charged™ low-emission products."

    some guys are right on key here. strato charged uses less fuel, burns cleaner, so-on. it simply uses what chevrolet started years ago with their vortech engines. fuel atomization. then ford with their triton which came in cars in 92 before any truck had it, then dodges magnum and so-on. gasoline won't burn in liquid form. this is why you can set a pail of gas on fire and only the top of it burns, not all of it at once. it takes gasoline and oxygen together to form combustion. so they came up with inductions that use turbulance to mix the gasoline and air before it gets to the combustion chamber. their is alot more to it, but i'll stop here before it gets to long.
