Con­ti­nen­tal Aero­space Tech­nolo­gies cur­rently of­fers the widest range of cer­ti­fied diesel en­gines in GA. Con­ti­nen­tal has de­liv­ered more than 6,000 en­gines which have logged over 7.1 mil­lion flight hours. Con­ti­nen­tal diesels are grouped in three se­ries: CD100, CD-200 and CD-300.

The CD-100 se­ries in­cludes for­mer Thiel­ert Cen­tu­rion en­gines of 135 and 155hp which to­day are called CD-135 and CD-155. Th­ese are four-cylin­der, in-line en­gines with au­to­mo­tive roots. Fit­ted with tur­bocharg­ers, they are liq­uid cooled, have charge in­ter­cool­ers and FADEC (full-author­ity digital en­gine con­trol) and use a PSRU (pro­pel­ler speed re­duc­tion unit).

The CD-200 se­ries in­cludes the for­mer TD-300 se­ries en­gines, which are based on de­vel­oped ver­sions of the SMA en­gine. The CD-230 and CD-265 of­fer 234 and 265hp re­spec­tively. He­li­copter ver­sions (where ‘R’ stands for Ro­tor craft), the CDR-265 and 285 of­fer 264 and 287hp. Th­ese four-cylin­der, op­posed en­gines are of con­ven­tional aero en­gine lay­out, are di­rect-drive, air (and oil) cooled, have ex­haust tur­bocharger, and me­chan­i­cal fuel in­jec­tion (no elec­tron­ics!)

In 2017 Con­ti­nen­tal in­tro­duced the CD-300, a V6, 3.0 lit diesel en­gine pro­duc­ing 300hp. Like the CD-100S, it also has au­to­mo­tive roots. Two ex­haust tur­bocharg­ers are fit­ted (one per cylin­der bank) and the unit has dual FADECS, sin­gle lever power con­trol and a geared PSRU. It is EASA cer­ti­fied.

The ex-thiel­ert eight-cylin­der, 310hp cer­ti­fied Cen­tu­rion 4.0 lit has been dis­con­tin­ued.

The CD-100 se­ries diesel en­gines have over­come teething prob­lems with PSRU and the TBR (time be­tween replacemen­t, note) has risen to 2,100 hours. The main­te­nance in­ter­vals for the CD-100 se­ries were ex­tended sig­nif­i­cantly fol­low­ing the in­tro­duc­tion of a new fly­wheel and clutch unit (ef­fec­tively the tor­sional vi­bra­tion damper) in 2010. www.con­ti­nen­tal­mo­tors.aero/ diesel

This en­gine from the UK, man­u­fac­tured by CKT Aero En­gines ltd, was show­cased two years ago at AERO in Ger­many. The four cylin­der, liq­uid-cooled, op­posed, geared en­gine, with 2.0 litre dis­place­ment de­vel­ops 240hp (take­off)/200hp (con­tin­u­ous) and is based on the Subaru EE20 au­to­mo­tive en­gine. The CKT-240TD has four valves per cylin­der and is fit­ted with tur­bocharger, in­ter­cool­ers and ra­di­a­tor. It has sin­glelever FADEC op­er­a­tion, dual al­ter­na­tors and pro­gram­mable ECU. The com­pet­i­tively priced en­gine pack­age weighs in to­tal 230kg, is now in se­ries pro­duc­tion and is de­liv­ered as a fire­wall-for­ward as­sem­bly com­plete with en­gine mount, tar­geted at the home­builder/ Ex­per­i­men­tal mar­ket. The en­gine can be op­er­ated on Jet A1 or au­to­mo­tive diesel fuel. www.ck­taero­engines.com
