Brief Description of the Invention:

Supercharger Kit greatly improves traction performance of a very common 50cc -350cc four-stroke engine. The Supercharger (air compressor) as a main unit of the Supercharger Kit supplies the naturally aspirated engine with as much as additional 50% to 150% fresh air. Engine power and torque increase accordingly. Video clip with 50cc minibike Honda Monkey Z50/AB27 street tests -- Link

Full Description of the Invention:

By supplying compressed fresh air the proposed Supercharger Kit dramatically improves performance of an internal combustion engine used for 50ññ – 350cc mopeds, scooterettes, mini-motorcycles, motor bikes and scooters. Our team has come up with inexpensive air pumps, which offers power boosting and torque increase of up to 150% for a number of bikes of different displacements (50ññ-350ññ).

Our team targets a very common bike (Pic. 1. 50cc Target Bike.jpg) powered by a single-cylinder, carburetor, 50cc, four-stroke engine like Z50J, AB27, 1P39FMB, 139FMA, ZS139FMB, 1P39FZA and other similar engines. The bike got additional gadgets to measure its performance parameters.

Conditions and requirements to conduct R&D and actually develop the Supercharger Installation Kit are as follows:
1. Use only a bike coming from the mass production assembly line.
2. The vehicle operator should be able to mount the installation kit easily.
3. No parts of the target bike, especially of its engine are modified except changing the main jet of a carburetor.
4. Upon request an operator is able easily dismount the kit and return the target bike back to its original state.

R&D consisted of the following steps.

Step 1. The target bike (VIN Code Z50J-23020**) gets additional gadgets and road tests in order to measure a number of its performance characteristics and some other parameters. Pic. 1. 50cc Target Bike.jpg is a picture of the target bike.

Step 2. A newly designed, fabricated, and tested Supercharger fits the given engine productiveness. All our supercharger designs are true positive pumps, so they can be used specifically for a given engine type with a preliminary determined OEM (“passport”) displacement.

2. 50cc_Charger_1.jpg, 3. 50cc_Charger_2.jpg present two pictures of the in-house-developed supercharger (see picture below).

Step 3. The target bike gets its own Supercharger Installation Kit. Its design meets the above-mentioned requirements and conditions 1-4.

6. 50cc_Kit_photo1.jpg, 7. 50cc_Kit_photo2.jpg are pictures of the mounted Supercharger Kit on the target bike

Step 4. In order to evaluate performance characteristics and other operation parameters of both the original (target) and modified bikes we developed proper for 50cc engine measuring methodic, consisting of A, B, C sub steps:
A. The 50 cc bike without any modifications was tested paying special attention to its acceleration parameters.
B. Then the same bike got a very common way of tuning, e.g. its piston-cylinder group was replaced with the one of 75cc. Test also targeted acceleration parameters as well as some other characteristics like productiveness.
C. The bike returns to its original state and is tuned by installing the Supercharger Kit on it.

Step 5. Conclusions
Based on the above described latest experience and experiments the installation of the Supercharger Kit is more preferable in terms of acceleration than deep tuning, which assumes the cylinder-piston group replace. It is important to note that the installation is done by the bike operator. The modified supercharged bike requires an operator to get adjusted to the new riding habits, which in turn means more riding fun. HM 50cc Pilot Report.doc is a document that features those new skills of riding the supercharged bike and has been provided by the experienced motorcycle person after actual test-driving. This report is available upon request.

This project met all the originally set requirements for the Supercharger Kit to be accounted during its development, design, and manufacturing. Prime objective was to keep the overall cost of the modification as low as possible. As result in particular, the project outcome proves that deep tuning costs at least twice as much as the Supercharger Installation Kit.

Forecast. Further supercharging achievements
There are other ways of tuning. The installed Supercharger reduces acceleration time by half. As a part of this project, the further acceleration time decrease is available due to additional supercharging. More acceleration time decrease (we presume -- up to 4 seconds!!!) is possible only at the expense of additional significant funding, that we do not have, and stress increase of the main 50cc engine parts.

Our expertise proves the ability to develop and manufacture a Supercharger Kit practically for any vehicle powered by four-stroke carburetor small (50cc-350cc) engine within short period. Since the market of such transportation means is huge, the kits mass production guarantees fast return of investment.

As an R&D team, we are looking for the cooperation with individuals/entrepreneurs/business entities/manufacturers for advancing this project to the market. Collaboration on J-V basis for full-scale interaction for the Supercharger Kit mass production (Investment and Profitability matrix are available upon request) is expected to successfully combine out engineering expertise with the prospective partner investing experience.
