      <title>COMBUSTION AND POLLUTANT FORMATION IN AN INDIRECT INJECTION DIESEL ENGINE</title>
      <link>https://trid.trb.org/View/199538</link>
      <description><![CDATA[A traversed fast-sampling technique has been applied to explore the processes of combustion and pollutant formation in an indirect injection, swirl chamber type diesel combustion system.  To permit traversed gas-sampling in each chamber, experiments were made on a double-scavenged two-stroke cycle engine with a simulated two-dimensional chamber configuration.  Parameters of interest in the experiments include the extent of fuel rich zones and their decay with time, the action of swirling air motion, nitric oxide formation, the formation of hydrocarbons and soot, the state of gas outflow from the swirl chamber into the main chamber, and flame spread within the main chamber.  The effect of certain operating conditions and design parameters, such as overall fuel-air ratio, injection timing, connecting passage dimension, and fuel spray direction on experimental parameters were investigated.]]></description>

      <title>EXPERIMENTS ON CYLINDER PRESSURE PULSATION AND DISTRIBUTION IN A SWIRL-CHAMBER-TYPE AUTOMOTIVE DIESEL ENGINE: IDLING KNOCKING NOISE INDUCED BY NON-UNIFORMLY DISTRIBUTED CYLINDER PRESSURE PULSATION</title>
      <link>https://trid.trb.org/View/204872</link>
      <description><![CDATA[The generation mechanism of the knocking-like, characteristic engine noise in a swirl-chamber-type, automotive engine was investigated.  This characteristic engine noise was particularly dominant in cold weather and at idling conditions.  It was found that in cold weather, cylinder pressure pulsations of significant amplitude can be induced in the main chamber by the cavity resonance of the swirl chamber and throat, but the pulsations distribute non-uniformly on the piston top surfaces.  Collisons between the pistons and the cylinder liners were induced by the pulsating, non-uniformly distributed cylinder pressure, therefore engine structure noise was generated.]]></description>

      <title>INVESTIGATIONS ON A PASSENGER CAR SWIRL-CHAMBER DIESEL ENGINE USING DIFFERENT ALCOHOL FUELS</title>
      <link>https://trid.trb.org/View/189762</link>
      <description><![CDATA[Investigations on the suitability of various alcohol fuels as alternatives to conventional diesel fuel were carried out on a passenger car swirl-chamber diesel engine. The test results with a methanol and an ethanol diesel fuel blend show that without alternation of the engine adjustment a good performance behaviour is obtained. In addition to a reduced soot emission and a considerably lower particulate emission the thermal efficiency mainly in the upper load range is higher than with pure diesel operation. The increased HC and CO emissions occuring at low loads can be avoided and a further improvement in energy consumption can be realized by adapting the injection timing for alcohol blend operation. A complete substitution of the diesel fuel with a methanol-ignition improver mixture necessitates an adpated and alcohol-resistant fuel injection system. A soot free combustion and with the exception of the NOX emissions nearly the same low level of gaseous pollutants as with pure diesel operation are achieved. In the full load range the thermal efficiency of the alcohol engine is distinctly higher, whereas at part load the efficiency turns out to be lower. With regard to the engine efficiency and the HC and CO emissions at low loads a further optimization of the fuel injection system is necessary.]]></description>
