TL;DR: In this article, a single cylinder four stroke air cooled direct injection (DI) diesel engine was used to investigate the NOx emissions with the help of Exhaust Gas Recirculation (EGR).
Abstract: Bio-diesel is an alternative fuel to diesel and is widely used in CI engines to reduce exhaust gas emissions which in turn helps in reduction of environmental degradation. But the problem with Biodiesel usage results in higher NOx emissions when compared to diesel engines. The objective of this work is to reduce the NOx emissions with the help of Exhaust Gas Recirculation (EGR).To investigate this, a single cylinder four stroke air cooled direct injection(DI) diesel engine was used. HC, CO, NOx and smoke concentration of the exhaust gas were measured to estimate the emissions. Various engine performance parameters are carried out and analyzed for different Bio-Diesel blends and neat Diesel. Results show reduction in NOx emissions with the help of EGR with little compromise in power output.

TL;DR: In this article, the effect of biodiesel on engine power, economy, durability and emissions including regulated and non-regulated emissions, and the corresponding effect factors are surveyed and analyzed in detail.
Abstract: As a renewable, sustainable and alternative fuel for compression ignition engines, biodiesel instead of diesel has been increasingly fueled to study its effects on engine performances and emissions in the recent 10 years. But these studies have been rarely reviewed to favor understanding and popularization for biodiesel so far. In this work, reports about biodiesel engine performances and emissions, published by highly rated journals in scientific indexes, were cited preferentially since 2000 year. From these reports, the effect of biodiesel on engine power, economy, durability and emissions including regulated and non-regulated emissions, and the corresponding effect factors are surveyed and analyzed in detail. The use of biodiesel leads to the substantial reduction in PM, HC and CO emissions accompanying with the imperceptible power loss, the increase in fuel consumption and the increase in NOx emission on conventional diesel engines with no or fewer modification. And it favors to reduce carbon deposit and wear of the key engine parts. Therefore, the blends of biodiesel with small content in place of petroleum diesel can help in controlling air pollution and easing the pressure on scarce resources without significantly sacrificing engine power and economy. However, many further researches about optimization and modification on engine, low temperature performances of engine, new instrumentation and methodology for measurements, etc., should be performed when petroleum diesel is substituted completely by biodiesel.

TL;DR: Compared with conventional diesel fuel, diesel-biodiesel blends showed lower carbon monoxide (CO), and smoke emissions but higher oxides of nitrogen (NOx) emission, however, compared with the Diesel fuel, NOx emission was slightly reduced when EGR was applied.
