COMMENTS

For the first time, this reporter was able to determine the engines declared for all the models. Comparisons will be made for both the 'A' models and the total number of engines declared.
  1. By far the most popular engine at this year's championships was the Yugov. Victor was doing much of the design work for Vorobiev some years ago. I first saw Victor with his bar-stock engines at the 1994 Championships in Shanghai. Sometime after the side exhaust Vorobiev was introduced, Vorobiev decided to leave the engine business. Victor took over the reins. The first Yugov was built on the Vorobiev crankcase. The performance of the engines has increased ever since. In Germany, 16 Yugov engines were used for the 'A' models from 42 teams. This year because of travel problems there were only 30 teams but there were still 11 engines being used for their first choice. The French team of the Surugue Brothers, Pascal and Georges, set a new heat record of 3:09.6 in one of the semi-final races. They went on to win the finals with a 6:42.7. There were at least a total of 31 Yugov engines at the 2004 WC. The Yugov was used in 3 of the top 5 and 6 of the top 12 finishers. I think it can be said that the Yugov with its integral, blind-bore sleeve is a winner. (Fig. 1)
  2. The second most popular engine was the Lerner with six being used as first choice. Bondarenko and Lerner were not in attendance at this Champs due to travel problems. The new Lerner seems not much different from the earlier one except that it sports a new shiny finish. The highest placing for the Lerner was by the Smith/Brown team of Great Britain in 7th place. There were 16 Lerners of different vintage declared at this contest. (Fig. 2 & Fig 3)
  3. The third most popular engine was the Mazniak with five being used as first choice. Yakov has modified his design and the engine now has an integral-finned sleeve. I didn't check but it also appears to have a blind bore. The Samuelsson/Axtilius team was 6th this year with a new Mazniak. They also placed 6th in Germany but their time has gotten a little better. The number of Mazniaks used was less than the 2002 CLWC . We'll have to see if the new changes can help its popularity to go back up. The total number of Mazniaks that were declared was sixteen. (Fig. 4)

    4. The next engines in popularity were the Profi and the Zalp, each with two used as first choice and each with a total of seven declared.
  4. The Profi has also been re-designed by Yury Chaika who teamed with old Master Valery Kramarenko to place 2nd. Their semi-final time was a very respectable 3:15.3. They were using the only retract-geared model at the champs. The engine appears to perform better than the previous design and is less expensive than the Yugov and some of the other engines. It will be interesting to see if it gains in popularity. The Profi also sports a new shiny finish. (Fig. 5)
  5. The Zalp that was used appears to be the 1999 design that appeared in France in 2000. It was used here by the Russian team of Averine/Martchenko for 8th place and the Italian team of Martini/Menozzi for 10th place. There were a total of seven Zalps of different vintage declared. (Fig. 6)
  6. The next engine was the Suraev. The best finish was by the Shabashov/Ivanov team with 3rd place. Vladimir Ivanov has been working with Suraev recently and has apparently modified the engine using the new case that was introduced around 2000. They turned the fastest heat time of 3:12.4 and the second fastest semi time of 3:11.5. They did not get a final time as they were DQ'd. The Suraev/Ivanov engine is shown in Fig. 7. The other team using the Suraev was Ascher/Ascher of the USA. Two of their engines are shown in Fig. 8 & Fig 9.
  7. Tim Gillott of the USA was using a very much modified Nelson. He has re-engineered it with an integral-finned cylinder and has produced a blind bore in a unique manner. He machines and fits the piston and open liner as usual then presses in the head. He also machined a new backplate and chromed it. The drum is drilled off-center to balance for the intake port opening. (Fig. 10)
  8. The last engine was an old Vorobiev side exhaust engine used by the Singapore Junior flyers. The photo is an archive photo. ( Fig. 11)
  9. As an extra treat, Bengt-Olof Samuelsson presented a bar stock example of a Mazniak for photos, Fig. 12. This is made by Jan Gustafsson.
