The effects of port injected n-heptane equivalence ratio and iso-octane direct injection timing are investigated experimentally and numerically. The results indicate that the combustion mode of iso-octane is dependant on the iso-octane direct injection timing corresponding to the stage of n-heptane HCCI combustion. In case of direct injection before the low temperature reaction of n-heptane, premixed combustion of the iso-octane occurs. In case of direct injection at the NTC period or the initial high temperature reaction stage of n-heptane, the iso-octane mainly undergoes premixed combustion.

Results showed that L-THP possessed negative inotropic and negative chronotropic action, lowed left ventricular pressure and it's infinitesimal calculus, decreased heart output in per min., shorten 〓 and 〓 of action potential of ventricular papillary muscle of guinea pig and even the plate-phase of action potential disappeared in larger dose group , but prolonged 〓. we studied transmembrane transportation of 〓 after administering L-THP , L-THP not only depressed uptake and increased release of Ca 2+ in normal myocardium, but also it showed stronger inhibition in cell injured by ISO, and fully eliminated the effect of ISO increasing uptake and decreasing release of 〓. By detecting the 〓 content of ventricular single myocyte using fluorescent probe Fluo-3/AM, results correspond to that done above, L-THP decreased 〓 content inside of cell significantly. Using whole-cell mode, we observed the effect of L-THP on Ica in ventricular single cell, it was found that L-THP decreased Ica, the effect increased with increasing it's dose, and had voltage, frequency-dependency. Dose highly corelated to effect, corelative constant is 0.87. When washing cell with normal tyre's solution, Ica could recover, which proved the blocked action of L-THP on calcium channel once again. Meanwhile, L-THP reduced production of MDA in heart injured by ISO in dose-dependent manner, improved content of GSH-Px, in case tissue or cell free from free radical damage.

RESULTS: Compared with NS control group, the ratio of HW/BW, LVW/BW and the content of hydroxyproline, AngⅡ, MDA and iNOS activity in the left ventricle were significantly increased. The cNOS, SOD, GSH-Px activities and NO content were obriously decreased in the ISO model group. After treatment with PNS, the left ventricular NO content, cNOS, SOD and GSH-Px activities were markedly higher than those in ISO model group. The content of MDA, AngⅡ and iNOS activities and the ratio of HW/BW, LVI were significantly lower than those in ISO model group.
