Patent number: 9790854Abstract: When only smoke is generated, the sensor sensitivity is not substantially changed from the initial value. When both smoke and unburned HC are generated, the number of times the sensor sensitivity becomes lower than the initial value is increased. From these results, it can be understood that a deposit is formed in the presence of unburned HC and smoke existing simultaneously. The degree of reduction in sensor sensitivity becomes higher if the smoke concentration is increased when the unburned HC concentration condition is fixed. From this result, it can also be understood that while the coexistence of smoke and unburned HC is a prerequisite, unburned HC contributes largely to the formation of a deposit.Type: GrantFiled: March 20, 2015Date of Patent: October 17, 2017Assignees: Toyota Jidosha Kabushiki Kaisha, Kabushiki Kaisha Toyota JidoshokkiInventors: Kouseki Sugiyama, Sho Sakurai

Publication number: 20150034061Abstract: An object of the present invention is to reduce the difference between the torque generated by an internal combustion engine and a required torque in a control system for a multifuel internal combustion engine that can use CNG and liquid fuel. To achieve the object, the control system for an internal combustion engine according to the present invention causes the internal combustion engine to operate in a first operation mode in which only CNG is used, when the required torque of the internal combustion engine is equal to or lower than a threshold and to operate in a second operation mode in which at least liquid fuel among CNG and liquid fuel is used, when the required torque of the internal combustion engine is higher than the threshold and changes the magnitude of the threshold in conjunction with the concentration of inert gases contained in CNG.Type: ApplicationFiled: February 9, 2012Publication date: February 5, 2015Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Masahiko Masubuchi, Satoshi Taniguchi, Kouseki Sugiyama, Hiroshi Eto

Patent number: 8257583Abstract: A fuel separation apparatus comprises a stock fuel storage tank storing stock fuel, a separator provided with a separation film separating the stock fuel into high octane value fuel with an octane value higher than the stock fuel and a low octane value fuel with an octane value lower than the stock fuel, and a high octane value fuel storage tank storing the high octane value fuel separated by the separator. When the temperature of the separation film is lower than the high octane value fuel separation temperature, the high octane value fuel stored in the high octane value fuel storage tank is supplied to the separator. Due to this, vaporization of fuel is suppressed and the fuel can be quickly raised in temperature. Due to this, a vehicle mounted fuel separation apparatus able to quickly raise the temperature of the fuel supplied to the separation film so as to quickly raise the temperature of the separation film at the time of engine cold start can be provided.Type: GrantFiled: December 22, 2008Date of Patent: September 4, 2012Assignees: ExxonMobil Research and Engineering Company, Toyota Jidosha Kabushiki KaishaInventors: Randall D.

Patent number: 8211300Abstract: A vehicle-mounted fuel separation system 24 is provided with a fuel heating device 56 heating stock fuel and a separator 57 separating stock fuel heated by the fuel heating device into a plurality of types of fuel. Furthermore, a forced exhaust device 66 forcibly exhausting the fuel in the fuel heating device from the fuel heating device when the temperature of the fuel in the fuel heating device becomes a reference temperature or more or is expected to become a reference temperature or more is provided. Due to this, a fuel separation system where excessive heating of the fuel by the fuel heating device of the fuel separation system is prevented is provided.Type: GrantFiled: December 22, 2008Date of Patent: July 3, 2012Assignees: ExxonMobil Research and Engineering Company, Toyota Jidosha Kabushiki KaishaInventors: Randall D.

Patent number: 8051828Abstract: A fuel management system mounted on a vehicle is operative to feed individually or a mixture of grades of relatively low, intermediate, and high autoignition temperature fuels to an associated internal combustion engine. The system includes an on board separation unit (OBS unit) for receiving and separating intermediate autoignition temperature (IAT) fuel into low and high autoignition temperature fuels, LAT and HAT, respectively. The production rate of the LAT and HAT fuels by the OBS unit is controlled to substantially match the consumption requirements of the engine at any given time for the LAT and HAT fuels.Type: GrantFiled: December 9, 2008Date of Patent: November 8, 2011Assignee: ExxonMobil Research and Engineering CompanyInventors: Bhaskar Sengupta, Krishnan Kumaran, Walter Weissman, Randall D.

Publication number: 20080006333Abstract: A multi-fuel system includes a high vapor pressure fuel tank and a low vapor pressure fuel tank. The high vapor pressure fuel tank contains a fuel a saturated vapor pressure of which is high so that the concentration of fuel vapor in a vapor space of the tank in the normal temperature range becomes higher than an upper-limit of an ignitable concentration of vapor. The low vapor pressure fuel tank contains a fuel a saturated vapor pressure of which is low so that the concentration of a fuel vapor in vapor space of the tank in the normal temperature range becomes lower than the upper-limit of an ignitable concentration of vapor. The vapor space in the high vapor pressure fuel tank communicates with the vapor space in the low vapor pressure fuel tank through a communication pipe, and the vapor space in the low vapor pressure fuel tank is connected to canister 15 through a vapor pipe and a check valve.Type: ApplicationFiled: June 27, 2006Publication date: January 10, 2008Applicants: ExxonMobil Research and Engineering Company, Toyota Jidosha Kabushiki KaishaInventors: Randall D.
