“…Nissan apparatus for (a) calculation of the heat transfer, (b) measurement of the heat transfer by boiling in a limited area, (c) measurement of the heat transfer by condensation and (d) visual observation of condensation inside the tube. 41 the test rig using a 0.667 l single-cylinder engine is shown in Figure 9. The main findings of the paper (which confirmed the work of Leshner 6 ) were that, in comparison with the liquid-cooled equivalent, an EC system enhanced the brake power, allowing more rapid warming up, better fuel economy and increased engine durability.…”

“…It is for example, particularly surprising that the system reported in [52] never made it to production. The answer to why none of the systems discussed were taken up, point to several significant challenges yet to be addressed.…”

“…The work focused on improving understanding of the conditions that lead to the onset of film boiling. As shown in Figure 2, A Nissan sponsored study on EC systems is reported in [51][52]. The 1987 SAE publication [52] is rich with experimental data and analysis on different aspects of EC systems and its effect on internal combustion engine performance.…”

“…As shown in Figure 2, A Nissan sponsored study on EC systems is reported in [51][52]. The 1987 SAE publication [52] is rich with experimental data and analysis on different aspects of EC systems and its effect on internal combustion engine performance. For example, from a cylindrical pool boiling type rig, both the temperature gradient within the cylindrical portion, and the vapour temperature, were measured and correlated with calculated wall surface temperature values and gradients, heat transfer coefficients, and the heat flux levels.…”

The evaporative cooling system concepts proposed over the past century for engine thermal management in automotive applications are examined and critically reviewed. The purposes of this review are to establish the evident system shortcomings and to identify the remaining research questions that need to be addressed to enable this important technology to be adopted by vehicle manufacturers. Initially, the benefits of the evaporative cooling systems are restated in terms of the improved engine efficiency, the reduced carbon dioxide emissions and the improved fuel economy. This is followed by a historical coverage of the proposed concepts dating back to 1918. Possible evaporative cooling concepts are then classified into four distinct classes and critically reviewed. This culminates in an assessment of the available evidence to establish the reasons why no system has yet been approved for serial production commercially. Then, by systematic examination of the critical areas in evaporative cooling systems for application to automotive engine cooling, the remaining research challenges are identified
