Imagine an engine that's 30 percent smaller than a traditional piston design of like output, and that runs smoothly, with less noise and vibration. Plus, it burns several types of fuel. That's the LiquidPiston X rotary engine, which was recently demonstrated powering a go-kart. The LiquidPiston rotary engine is a non-Wankel design that we've featured on Gizmag before. Back inthe company announced the engine's development. Now it's showing the new engine with a novel application to showcase its power-to-weight capabilities.
The LiquidPiston X Mini shown in the video at the bottom of the page has nearly 2 horsepower per pound 3. It's 30 percent smaller and lighter than the equivalent spark-ignited gasoline engine it replaces, and can be up to 75 percent smaller than a like-output diesel engine.
Even better, the engine's design means that it has no poppet valves and exhaust is balanced through over-expansion, removing the need for a muffler. The X rotary engine can be as much as 20 percent more fuel efficient than its gasoline counterpart and 50 percent more efficient than an equivalent diesel engine. The design, says the company, is scalable from 1 horsepower to over 1, The X Engine is designed as a unique rotary that has three combustion events per rotor revolution, explaining its high power density and balanced operation.
The engine is designed to be made with 2-dimensional manufacturing methods, making it simple to build. This also means that it can be easily modified by enthusiasts — something that LiquidPiston is expecting, having released a developer's kit for the X Mini.
One of the secrets in the X Engine's design is the unique rotary cycle. Unlike a Wankel rotary, which uses a triangular center rotor, the X Engine has an oval-shaped rotary which rotates in a cloverleaf-like core. This creates higher compression with better seals and exhaust pressure.
It also creates a larger expansion volume than compression volume, similar to the high-efficiency Atkinson Cycle engine used in hybrid vehicles.
In larger versions of the engine, LiquidPiston says, water can be injected into chambers after the exhaust cycle to cool the engine when under high loads. The engine being used in the video to power the go-kart is a four-stroke 70cc gasoline version that produces about 3. LiquidPiston expects to have the engine producing 5 hp 3. Source: LiquidPiston.

View 4 Images.What we have up for bids here is a good usedSachs Wankel KM24 cc rotary engine as shown below. We just bought out a hanger and obtained this engine with many more other engines and projects and this is the tenth engine to go.
This engine was a spare for a customer of ours who was running another KM24 rotary. This engine would be for the guy who is running a KM24 and looking for a spare engine or maybe for the guy who is looking for a Wankel engine for a period correct restoration or rotary engine for another application.
These KM24's are getting harder and harder to find, so if you need or want this engine, dont miss out. Now here is the full specs and whats included with the engine. This is the 23hp cc version. PTO spins counterclockwise as viewed looking directly down on the end of the engine.
It can also be ran in both tractor and pusher applications. Engine is in good overall running and mechanical condition. Engine is ready to bolt up and use on any application. As I noted above these KM24s dont come up often, so if you are currently running one of these engines and want a spare or need a small Wankel engine for another application, dont pass this engine up.

This sneak preview of the Meriva concept to be unveiled at the Geneva Motor Show reveals suicide-style rear doors that will be a production certainty for the next-gen Meriva. The mini-MPV will retain its B-pillar so that structural integrity is maintained and so the rear doors can be opened independently of the front ones.

The engine, a 5 hp air-cooled rotary engine, incorporates advanced materials and technology and has a bespoke fuel injection system. This advance release enables airframe manufacturers to evaluate and package the engine, with a view to production models being available in months time.
Birmingham, UK April 2, -- Cubewano announce the release of the pre production development version of its 5 hp heavy fuel engine.
The engine is a lightweight, fuel injected, 5 hp, air cooled, single rotor internal combustion engine of the Wankel rotary type. After many months in development Cubewano are finally happy with the performance of their 5 hp engine to release it for sale. The engine in many respects advances the technology of the Wankel rotary engine by utilising advanced materials including ceramics and specialist coatings to achieve an extremely lightweight 1.
The engine is designed to use a recirculating oil system and a lightweight ECU, about the size of a matchbox. However, for development purposes, Cubewano have been using a full size ECU and pre mix lubrication. The decision to release the pre-production version is to enable airframe manufacturers to get a head start testing and packaging the Cubewano engine. About: Cubewano, formed indesign and manufacture small, high quality, high power-to-weight ratio internal combustion engines, currently in the 3 to 7 hp range, with multi-fuel capability including Kerosene also known as JP8, JET-A1 and Heavy Fuel.

The Rotapower engine is ideal for converting contaminated biogas into electricity. It's resistance to hydrogen sulfide and siloxane reduces overall operational and maintenance costs in CHP systems. A Rotapower generator can provide dispatchable power for microgirds and renewable energy production.
Using carbon neutral fuels, this is low cost and environmentally friendly alternative to industrial battery systems. Electric vehicle market penetration has been limited by range anxiety of consumers. A Rotapower range extender can overcome this barrier, and because of its small volume and high power density, it will not impact vehicle design constraints. Small personal aircraft can benefit from the high power to weight ratio and small volume, providing far more longevity and safety compared with battery-based propulsion systems.
Improved emissions, small volume and high power make the Rotapower engine a excellent alternative powerplant for personal watercraft. Small engines with low emissions and high performance over competing engines make the Rotapower a ideal powerplant for small 2-wheeled vehicles.
Because of the Rotapower engine's small size and high power density, small portable generators become more practical for widespread use in rural communities worldwide.

Exhaust porting includes both exhaust ports turbo housings only. Engine Core Charge:. Engine Option If you are ordering a engine make sure you select this option. The rotating assembly includes both rotors, main pulley, front and rear counterweights, and the eccentric shaft. These gears have had several machining modifications performed, as well as heat-treating of the teeth to improve fatigue resistance and yield strength, includes a three-window bearing and is intended for high power output racing engines.
The clearancing machining process removes material from both sides of the rotor to minimize the likelihood of contact with the side housings in high horsepower, high RPM engines. These MFR rotor bearings are manufactured with a deep groove for additional oil storage and offer an additional. More accurate tensioning of engine. Less chance of bolt breakage. High quality point nuts rated atPSI tensile strength. Studs manufactured from chrome moly, heat treated, centreless ground and black oxided.
Note the standard factory manual flywheel cannot be used with the Stud Kit. Rotor housing deflection reduced - increases apex seal life.
Less material machined from housings and plates than with doweling, reducing the possibility of cracking. High boost engine expansion reduced. Studs are less prone to stretching under high boost applications. Related Items. Stage 2 Rebuilt Rotary Engine. Stage 3 Rebuilt Rotary Engine.
