WHAT'S NEW
| U.S. Patent allowed for issuance on October 3, 2007. |
Patent application 11/139,745, with a filing date of 5/27/2005, was allowed for issuance on October 3, 2007, with all the 23 claims granted. It covers, in detail, the Variable Compression Ratio (VCR) Piston Engine and shows that it works by implementing stiff disc-springs with a high level of pre-loading (greater than 50%). It is the first patent to show that the present form of VCR cannot work, e.g. by Ford, F.M., etc., and that the correct form is shown in great mathematical detail in the disclosure.It can give a 15% fuel economy improvement at light loads, and higher power and higher efficiency at wide open throttle (WOT).

April, 2007. Production Prototype. |
CEI completed the production prototype of the patented CEI Ignition, and successfully completed three units in April, 2007, one of which was delivered to Champion/FM. This is the most advanced system developed by CEI, having two 8-pin micro-controllers, one in the ECU and one in the Ignitor, giving greater flexibility and versatility. The units have the same five times greater energy of 150 mJ (versus 30 mJ) despite having the same coil size. The output peak voltage is 45 kV (versus 36 kV) despite having half of the turns ratio (58 versus 116). The efficiency is twice as great despite having the preferable lower peak current of 350 ma (to reduce plug erosion), and give several other advantages. |

U.S. Patent 7,182,077
Issued to CEI on 2/27/07 |
February 27, 2007. U.S. Patent 7,182,077 “High Energy Density Inductive coils … for Lean Burn Engines” was issued to CEI. The priority date is May 24, 2005. It was allowed for issuance September 7, 2006, with all 20 claims granted on first action. The patent improves the CEI coil with a peak current of about 300 ma, and also includes a coil design with a “scrappless” magnetic core. The ignition also includes plugs with Stainless Steel electrodes which produce glow discharge type sparks above 200 ma under quiescent engine conditions. |

U.S. Patent 7,178,513
Issued to CEI on 2/20/07
|
February 20, 2007. U.S. Patent 7,178,513, “MCU Based High Energy Ignition” was issued to CEI, with filing date April 19, 2002. It was allowed with all 28 claims granted. It is considered one of CEI’s most important patents on the CEI Ignition. It is a master patent when taken into account with CEI’s patents issued between 2000 and 2007, especially 6,142,130, issued 2000, and 7,182,077, issued February 27, 2007. The patent includes magnetically biased ignition coils and electronic circuitry, and an improvement of the halo-disc plug of CEI Patent 5,577,471. |

U.S. Patent 7,165,528
Issued to CEI on 1/23/07 |
January 23, 2007. U.S. Patent 7,165,528, “Two-valve High Squish Flow I.C. Engine” was issued to CEI, based on application filed April 19, 2002. It was allowed with all 24 claims granted, and is one of CEI’s most important patents on engine efficiency and emissions (global warming). It is a critical patent when taken into account with CEI’s patents issued between 2000 and 2007, especially Patent 6,267,107 B1, issued 2001. The patent includes independent firing of the twin plugs, air blast fuel injector systems, features of the GDI Engine, and spring actuated Variable Compression Ratio pistons and connecting rods. |
