“…According to Corkwell [8], who reviewed the existing published data from previous exhaust emissions testing on ethanol-diesel blends, the most frequent observations occurred around a 20% increase in the level of THC emission, a 20% reduction or no change in CO emission and almost no variation in NOx emission. Besides the regulated exhaust emissions, ethanol-diesel fuel blends could increase the emission of unburned hydrocarbons [9] and aldehyde emission [10].…”

“…The blends containing 83-94% diesel fuel, 5-15% ethanol, 1-3% additive and a small amount of commercially available cetane improver (o0.33% by volume) in the mixture could reduce 41% PM, 27% CO emissions from a heavy-duty diesel engine in laboratory and field tests (Ahmed, 2001). However, ethanol diesel blends increase unburned hydrocarbons (Shih, 1998;Cole et al, 2001), NO x emissions (Cole et al, 2001) and aldehyde emissions (Rideout et al, 1994;Gjirja et al, 1998). Moreover, the viscosity and lubricity of the blends decreases, cetane number linearly reduces at ambient temperature (Caro et al, 2001).…”

The addition of ethanol to diesel fuel simultaneously decreases cetane number, high heating value, aromatics fractions and kinematic viscosity of ethanol blended diesel fuels and changes distillation temperatures. An additive used to keep the blends homogenous and stable, and an ignition improver, which can enhance cetane number of the blends, have favorable effects on the physicochemical properties related to ignition and combustion of the blends with 10% and 30% ethanol by volume.The emission characteristics of five fuels were conducted on a diesel engine. At high loads, the blends reduce smoke significantly with a small penalty on CO, acetaldehyde and unburned ethanol emissions compared to diesel fuel. NO x and CO 2 emissions of the blends are decreased somewhat. At low loads, the blends have slight effects on smoke reduction due to overall leaner mixture. With the aid of additive and ignition improver, CO, unburned ethanol and acetaldehyde emissions of the blends can be decreased moderately, even total hydrocarbon emissions are less than those of diesel fuel. The results indicate the potential of diesel reformation for clean combustion in diesel engines. r

“…Studies on ethanol in the internal combustion engine are summarized in Table 4. Cole et al 46 reported that particulate emissions can be significantly decreased on about two-thirds of engine maps using 10% or 15% ethanol–diesel blends. Chen et al 47 recorded the combustion process of a direct injection optical diesel engine using a high-speed charge-coupled device (CCD) camera.…”

Soot is one of the main pollutants produced by incomplete combustion of hydrocarbon fuels, which poses a serious threat to human health and the urban environment. Alcohols have been generally considered to be a potential clean fuel to reduce soot emissions. At present, alcohol fuels represented by methanol, ethanol, butanol and pentanol have been extensively studied and have made remarkable progress. Therefore, this article is written as a broad overview of the subject. The effects of methanol, ethanol, butanol and pentanol additions on the formations of soot and polycyclic aromatic hydrocarbons were systematically summarized from the two aspects of the internal combustion engine bench and the fundamental combustion system. These studies have shown a decreasing or synergistic effect of alcohols addition on soot formation and initially revealed the mechanism of soot formation. However, the formation mechanism of soot in complex environments and the mechanism of the effects of alcohols on soot still need to be studied in depth, which can provide more opportunities for humans to reduce soot production during the combustion of hydrocarbon fuels. Finally, some challenges and research suggestions are outlined in the last section of this review.
