It is found that slight increase in brake power (BP) and higher brake specific fuel consumption (BSFC) are attained with butanol-biodiesel-diesel fuels, while brake thermal efficiency (BTE) is decreased. At full load, the results are indicated that 10% and 20% average reduction in carbon ...
Intracellular ROS increase levels inE. coliafter exposure to n-butanol [17]. We therefore considered whether introducing OmpC-fused TMT into butanologenicE. coliwould improve n-butanol tolerance and productivity. In the present study, we engineered theC. acetobutylicumn-butanol synthetic pathway intoE...
The reactions and corresponding enzymes for n-butanol production are outlined in Figure1. As enzymes with the same catalytic function from different organisms have different catalytic activity, ability to be expressed, solubility, etc., we sought to test a number of candidates for each reaction in ...

However, results showed also a decrease in VE, BP, Tq,Pand EGT when engine operated with the dual alcohols compared to base fuel. Nevertheless, performance of the dual alcohols can exceed those of the base fuel by increasing the blend rate value. Besides, dual alcohols burn cleaner than ...
Moreover, introducing the EHN in the blends increased the carbon monoxide (CO) up to 16.64%, hydrocarbon (HC) emissions up to 27.46%, brake power (BP) up to 5.62% and brake thermal efficiency (BTE) up to 2.5% compared to the n-butanol added biodiesel blends. On the other hand, the...
The results for 10 iso-BA-90 diesel showed a slight improvement in BP by 4% at medium speed, while the BP of 20iso-BA-diesel, 10 and 20 n-BA-diesel was slightly lower and comparable with pure diesel at all engine speeds. The highest peak in-cylinder pressure was measured for the ...

When the throttle opening is 10%, high engine speed operation will reduce brake power (BP), brake torque (BT) and BTE, and increase CO emissions. In terms of emissions, n-butanol gasoline blends can reduce CO and NOx emissions, but HC emissions increase. Finally, the results show that n...
