“ we have looked to gain performance by increasing the peak revs , and improving areas like cylinder filling and combustion , ” explained denis chevrier , renault ' s head of trackside engine operations . “ in qualifying trim , we expect a gain of several tenths of a second and the final dyno tests before the grand prix will allow us to determine exactly how much additional performance is available during the race “我們看上去已經通過增加最大轉數取得了成績，并改善了像汽缸填塞和燃燒這樣的區域”雷諾賽道引擎運作負責人丹尼斯-謝維瑞爾解釋說， “在排位賽中，我們期待能獲得零點幾秒的時間，大獎賽前的最后測試會允許我們最終決定可以在正式比賽中有多少的附加表現。 ”
Then following reality constituent of engine and connecting component interface , a nonlinear signal cylinder engine model has been created , though fire interval and fire order , a control - oriented four cylinders engine is build . following dynamometer is seen as load , performance of engine is simulated and researched under the condition of constant torque and speed , validation of the math and simulation model have been confirmed by comparison result between simulation with test result of engine performance simulation software dyno 按照發動機的實際組成，根據各部件的接口類型連接模型庫中的部件，建立了單缸發動機非線性模型，在此基礎上，依據發動機實際發火間隔和順序，建立了面向控制的四缸汽油機模型，并以測功器為負載，通過恒轉矩和恒轉速方式進行了發動機性能仿真和研究，仿真結果和發動機動力性能仿真軟件dyno測試結果的對比驗證了數學模型和仿真模型的正確性。
Furthermore , it is also verified by chassis dyno tests that lpg motorcycle has better emission performance than gasoline engine , and has better acceleration performance e . g . exceed acceleration than former gasoline engine , and has low noise level characteristics as well as has ability to achieve equivalent level fuel economy performance compared with former gasoline engine 整車動力性、經濟性和排放性轉鼓臺架試驗對比表明： lpg摩托車整體排放性能優于汽油摩托車；最高車速略有下降但加速性基本與汽油摩托車相同(超越加速性優于汽油摩托車) ； lpg摩托車具有良好的低噪聲特性，且整車燃料消耗率及其經濟性與原機基本相當。
Long - hole and geometrical proportion type of mixing unit is finally adapted in lpg supply system , and power and torque output of lpg engine are improved by increasing compression ratio , and ignition characteristic is tried to adjusted to satisfy engine performance . meantime emission performance and noise level of lpg engine at full - throttle and other various part - throttle operations are tested and compared with former gasoline engine . ( 3 ) it is verified by engine dyno tests that lpg engine has better synthesized performance at aspects of power and torque , fuel economy , as well as emission than former gasoline engine 選擇了等比例長孔式混合器控制空燃比；通過提高壓縮比來彌補動力性的損失；以動力性為主控目標，對最大功率點、最大扭矩點、中等轉速、最低轉速點所對應的發動機轉速做了點火特性的調節；通過空燃比的合理控制，直接改善發動機的動力性、經濟和排放指標；作為對缸內燃燒過程的理論分析，進行了燃燒特性的實驗測試；對原汽油機和新開發的液化石油氣發動機，進行了外特性和部分負荷特性以及怠速的排放及噪聲對比性測試。
For example the infrastructure of the technical center consists of engine dyno , chassis dyno , emission measurement and state - of - the - art product development and testing tools etc 該技術中心擁有發動機動態測量系統、底盤動態測量系統、排放測量及尖端產品開發和測量工具等先進的博世設備，著力于燃油噴射系統的匹配，是博世柴油系統在中國的研發基地。
New sports exhaust system with electronic programmable butterfly - valve control ( available in 2different sound levels ) . this cat - back performance exhaust system was developed on the dyno 新的運動型排氣系統由可編程的蝴蝶閥控制（有兩檔可以調節聲音的大小），使這個貓背式排氣系統的功效發揮到了極致。
